This program ensures the integrity and confidentiality of sensitive government and public sector data by rigorously validating cryptographic modules. Its operational framework is designed to provide a robust security metric for the procurement and deployment of secure IT systems.

Key aspects of KCMVP include the central role of the National Intelligence Service (NIS) in its oversight, the adoption of a multi-level security assurance model, and a distinct focus on validating domestically developed cryptographic algorithms. The program is also undergoing continuous enhancements, particularly in elevating security strength requirements and streamlining validation processes. KCMVP's comprehensive approach significantly contributes to South Korea's cybersecurity resilience, reflecting a strategic balance between national sovereignty in cryptographic standards and an evolving engagement with global security frameworks.

1. Introduction to the Korea Cryptographic Module Validation Program (KCMVP)
 

1.1 Defining KCMVP: Purpose and Scope

The Korea Cryptographic Module Validation Program (KCMVP) serves as South Korea's national certification system for cryptographic modules. Officially known in Korean as "한국형 암호모듈 검증제도" (Hanguk-hyeong Amho Module Geomjeung Jedo), which translates to "Korean Cryptographic Module Validation Program," or more broadly as "암호모듈 검증제도" (Amho Module Geomjeung Jedo), meaning "Cryptographic Module Validation Program," it is specifically designed to assess and confirm the security and implementation suitability of these critical components.  

The fundamental purpose of KCMVP is to guarantee the security of cryptographic modules used within security systems that protect sensitive information across computer and telecommunication networks. This mandate extends specifically to data exchanged through information and communication networks of government and public institutions, with a particular emphasis on important, albeit unclassified, information. By ensuring that these modules adhere to stringent requirements for data protection and secure communications, the program establishes reliability and trustworthiness in high-security environments. KCMVP's scope is broad, covering cryptographic modules implemented in various forms, including software, hardware, firmware, or any combination thereof.  

1.2 Significance in South Korean National Information Security

KCMVP holds profound significance within South Korea's national information security landscape. For information system owners, especially those within government and public institutions, obtaining KCMVP authorization for cryptographic modules is a necessary step to operate information systems safely. This effectively establishes KCMVP validation as a de facto or explicit requirement for modules deployed in these critical sectors.  

The certification process ensures that cryptographic solutions align with national security and regulatory guidelines, thereby fostering a high degree of confidence in the underlying security infrastructure across the nation. Through its rigorous validation of cryptographic modules, KCMVP directly enhances South Korea's overall cybersecurity posture and resilience, acting as a crucial defense mechanism against cyberattacks and data breaches.  
 

The program's explicit focus on "important but not classified information" indicates a sophisticated and expansive understanding of national security. This approach acknowledges that compromises of data, even if not traditionally deemed "classified," can still have substantial societal, economic, or operational repercussions. Such data might include administrative records, financial transactions, or personal identity information. By extending validation to this broad category, KCMVP aims to establish a pervasive baseline of cryptographic security throughout the public sector. This contributes to building a more resilient national digital infrastructure capable of withstanding a wider array of cyber threats and ensuring the continuity of essential public services and government functions.  

Furthermore, KCMVP's policy of validating specific Korean-developed algorithms, such as ARIA, SEED, LEA, and HIGHT, while historically excluding international standards like AES , represents a deliberate national strategic choice. This approach is designed to cultivate cryptographic self-reliance and safeguard the domestic industry. By prioritizing homegrown algorithms, South Korea aims to reduce its dependence on foreign intellectual property, mitigate potential supply chain vulnerabilities, and maintain greater control over the foundational security elements of its national infrastructure. This policy encourages local expertise, research, and development in cryptography, thereby strengthening national technological sovereignty in a critical security domain.  

2. Institutional Framework and Key Stakeholders

2.1 Governing Authorities and Their Roles

The National Intelligence Service (NIS; 국가정보원) serves as the central validation authority for the KCMVP. The NIS is entrusted with the ultimate responsibility for supervising the entire KCMVP program, including the establishment of necessary regulations and guidelines for cryptographic module validation. It also conducts the final review of test results and manages the official notification process for validated modules.  

A critical function of the NIS is the selection of specific cryptographic algorithms subject to KCMVP validation. This selection process is comprehensive, taking into account factors such as the algorithm's security strength, operational efficiency, alignment with standardization efforts, consistency with domestic and international cryptographic usage policies, potential for interoperability, and intellectual property considerations. The NIS’s role also involves convening a dedicated cryptographic validation committee. 

This committee meticulously deliberates on the test and validation results submitted by testing agencies before the official validation certificates are issued, ensuring a thorough assessment of each module's compliance and security posture.  

2.2 Accredited Testing and Validation Bodies

The KCMVP framework incorporates a network of accredited organizations responsible for conducting the technical testing and evaluation of cryptographic modules. These entities operate under the stringent guidelines established by the NIS and include both public and private sector bodies. Key governmental research institutions involved in the testing process are the National Security Research Institute (NSR; 국가보안기술연구소) and the Korea Internet Security Agency (KISA; 한국인터넷진흥원). The Korea Testing Association (TTA) has also been officially recognized for its competence as a cryptographic module testing agency, particularly for software cryptographic modules, by meeting the requirements outlined in the NIS's "Cryptographic Module Testing and Validation Guidelines". Additionally, qualified private testing agencies, such as Korea System Assurance (한국시스템보증), perform testing duties within the KCMVP ecosystem.

These private entities are subject to strict qualification criteria, including requirements for domestic presence and the employment of expert personnel, and undergo periodic re-evaluation to ensure ongoing compliance and competence.  

These testing agencies are tasked with executing comprehensive evaluations to verify that cryptographic modules comply with the detailed requirements stipulated in KCMVP's test standards. Following the completion of these tests, they are responsible for compiling and submitting detailed test result reports to the NIS for final validation.  

The institutional structure of KCMVP, with the NIS maintaining centralized control over policy and final validation while distributing the actual testing workload to multiple specialized agencies, represents a highly effective model. This design allows the NIS to ensure consistent adherence to national security priorities and standards. Simultaneously, it leverages the diverse technical expertise and scalability offered by various testing bodies, preventing bottlenecks and ensuring the program can efficiently handle a growing volume of validation requests. This distributed execution model enhances the program's efficiency and scalability, enabling it to process a larger number of modules while maintaining rigorous technical scrutiny, which is crucial for a national program with a wide mandate.

The stringent qualification requirements, such as domestic location and expert staffing, and the mandatory periodic re-evaluation for private testing agencies underscore a critical commitment to maintaining the integrity and reliability of the entire KCMVP ecosystem. This level of scrutiny for testing agencies is fundamental to the trustworthiness of KCMVP. If the testing phase were compromised by inadequate expertise, conflicts of interest, or outdated methodologies, the entire validation process would be undermined, potentially leading to the certification of insecure modules. By ensuring the consistent quality and impartiality of the testing inputs, the NIS reinforces the integrity of its final validation decisions. This robust quality assurance mechanism for testing bodies is a critical safeguard that underpins the reliability and international standing of KCMVP as a credible security assurance program.  

3. KCMVP Validation Process and Technical Requirements

3.1 Overview of the Certification Lifecycle

The KCMVP module validation system is structured as a comprehensive, multi-stage process, typically progressing through a total of seven distinct steps. The certification lifecycle commences with the cryptographic module developer submitting an application for validation to an accredited testing agency. Historically, this preliminary review phase has presented inconveniences for developers, often spanning several months due to reliance on email-based communication. To address this, KCMVP plans to introduce an online service in 2024, aiming to streamline and expedite this initial stage.  

Following the preliminary review, the selected testing agency, which could be KISA, NSR, or a qualified private firm, formally enters into a testing contract with the module developer. The core of the process involves the testing agency conducting thorough and comprehensive tests. These evaluations rigorously verify that the cryptographic module satisfies all the requirements specified in the KCMVP test standards. A key component of this phase is the testing of the implementation conformance of cryptographic algorithms, often utilizing specialized tools such as KCAVS (Cryptographic Algorithm Validation System).  

Upon successful completion of all required tests, the testing agency compiles a detailed test result report and formally submits it to the National Intelligence Service (NIS), which serves as the central validation agency. The NIS's dedicated cryptographic validation committee then undertakes a meticulous review and deliberation of the submitted test and validation results. This committee plays a critical role in assessing the module's compliance and overall security posture. As the final step, following the committee's investigation and approval, the NIS formally notifies the testing agency of the validation results.

Subsequently, the NIS publicly discloses the list of successfully validated cryptographic modules, making this information accessible to the public and potential users. 

 
3.2 Detailed Security Levels and Their Criteria

KCMVP employs a tiered security level system designed to provide varying degrees of assurance based on the sensitivity of the data and the application environment. These levels range from Security Level 1 to Security Level 4, with Level 4 representing the highest and most stringent security requirements. Significantly, these levels are cumulative, meaning that each higher level incorporates and builds upon all the requirements of the preceding lower levels, in addition to imposing more rigorous criteria.  

Beyond independent ratings for specific security areas, each cryptographic module also receives an overall rating. This overall rating is determined by the minimum of the independent ratings received across all evaluated areas. This approach ensures that the module's weakest link defines its overall security posture, promoting a holistic view of its security capabilities.  

Illustrative security level requirements include:
 

Security Level 2: Requires the implementation of tamper-evident physical security mechanisms. These mechanisms are designed to provide visible indications if attempts have been made to access or compromise the module.  
 

Security Level 3: Aims to prevent intruders from gaining access to sensitive information contained within the cryptographic module. This level mandates physical security mechanisms intended to have a high probability of detecting and responding to attempts at physical access, use, or modification of the module.  
 

Security Level 4: Represents the most robust physical security. At this level, the physical security mechanisms provide a complete protective envelope around the cryptographic module. The intent is to detect and respond to all unauthorized attempts at physical access, regardless of whether external power is applied. Penetration of the module's enclosure from any direction is expected to have a very high probability of being detected, resulting in the immediate zeroisation (secure erasure) of sensitive information.  
 

3.3 Approved Cryptographic Algorithms and Module Types
 

KCMVP validates a diverse set of cryptographic algorithm types essential for secure data operations. These categories encompass Block Ciphers, Hash Functions, Random Number Generators, Digital Signatures, Message Authentication Codes, Public Key Cryptography, Key Establishment schemes, and Key Derivation functions.  

A distinctive feature of KCMVP is its specific focus on and validation of domestically developed block cipher algorithms, such as ARIA, SEED, LEA, and HIGHT. Historically, international standard algorithms like AES were deliberately excluded from the validation scope. This policy was implemented to promote the use of South Korean-developed block ciphers and to protect and foster the growth of the local research and development and manufacturing industry.  

Modules undergoing KCMVP validation must meet specific security strength requirements. Current guidelines mandate a minimum of 112 bits of security strength. However, in a significant policy update, new applications for validation submitted from 2025 onwards will be required to support a higher minimum of 128-bit security strength. 

This mandatory increase in required security strength is a clear, proactive strategic move. Cryptographic security is an ongoing effort against increasing computational power and evolving attack methodologies. Mandating a higher security strength, such as a longer key length for symmetric algorithms, is a necessary response to ensure that cryptographic modules remain robust against attacks that become feasible with more powerful computing resources. 

This proactive update demonstrates that KCMVP is not merely reacting to current threats but is actively preparing its standards for the future. By setting a higher bar, it aims to extend the effective lifespan of certified modules and maintain the integrity of sensitive information for a longer duration, potentially reducing the need for frequent and costly re-certifications or replacements in the face of technological advancements.  

The validation program is applicable to cryptographic modules regardless of their implementation form, encompassing pure software modules, firmware-based modules, dedicated hardware modules, or hybrid combinations of these forms.  

3.4 Testing and Conformance Evaluation Procedures
 

The KCMVP validation process is holistic, assessing cryptographic modules across 10 key security areas. These include: cryptographic module specification, ports and interfaces, roles, services and authentication, finite state model, physical security, operational environment, cryptographic key management, self-tests, design assurance, and mitigation of other attacks. Each of these areas is independently rated.  

KCMVP adheres to and references specific verification and testing standards. It primarily applies the KS (Korean Standard) Cryptographic Module Security Requirements and KS Cryptographic Module Testing Requirements. Additionally, for certain specialized aspects, KCMVP refers to international ISO/IEC standards, such as those for non-invasive attack countermeasures, implementation conformance testing of cryptographic algorithms, and random number generator testing.

This dual-standard approach is a strategic compromise. By prioritizing domestically developed algorithms and national standards, South Korea reinforces its cryptographic sovereignty and supports its local industry, aligning with its broader national security objectives. However, by simultaneously incorporating or referencing ISO/IEC standards for testing methodologies and specific security functions, KCMVP ensures that its validation processes are technically sound, rigorous, and align with international best practices in areas where global consensus exists. This allows KCMVP to benefit from international research and development in testing and security evaluation techniques without compromising its national policy on core algorithm selection, potentially enhancing its credibility on the global stage while maintaining national control.  

Test reports submitted for KCMVP validation must strictly adhere to Korean Testing Standards (KS). The program explicitly states that it cannot accept test reports based solely on international standards like EN/FCC; testing must be conducted in accordance with Korean standards. Furthermore, comprehensive documentation is required, including product manuals in Korean, detailed wiring diagrams (including module wiring diagrams), and clear PCB placement diagrams with visible part numbers. The KCAVS (Cryptographic Algorithm Validation System) is a dedicated tool utilized to verify the accurate and proper implementation of cryptographic algorithms within the module. This process involves a meticulous review of 'Request' files (containing algorithm-related information), 'Fact' files (including corresponding output data and implementation conformance test results), and 'Response' files (containing the module's output data generated by executing the Request file).  

4. Strategic Benefits and Industry Impact of KCMVP

4.1 Advantages for Cryptographic Module Developers and Vendors
 

KCMVP certification is a crucial enabler for cryptographic module developers and vendors seeking to provide IT security solutions to South Korean government entities and critical infrastructure sectors. Obtaining this certification provides a significant competitive advantage, effectively opening access to these high-security and often lucrative markets. The rigorous validation process, coupled with the oversight of the National Intelligence Service, lends substantial credibility to KCMVP-certified cryptographic modules.

This serves as a powerful signal of their reliability, trustworthiness, and adherence to national security standards, significantly boosting customer confidence.  

Companies that integrate KCMVP-certified components or design their products with KCMVP compliance in mind can experience notable improvements in their development processes. For instance, Dream D&S, a South Korean information security company, by embedding a KCMVP-compliant key management system, achieved increased design and development efficiency, leading to a faster time-to-market for their high-quality security systems. By offering KCMVP-certified products, vendors enable their customers, especially government agencies and public institutions, to meet their own stringent data protection and regulatory compliance requirements more easily. This reduces the compliance burden for end-users, making certified products more attractive.  

KCMVP certification transcends a mere regulatory hurdle; it functions as a powerful market enabler and a strong, trusted signal of quality and trustworthiness for vendors operating within South Korea's public sector and critical infrastructure. For vendors, KCMVP certification is a strategic investment that unlocks access to lucrative and stable government and critical infrastructure markets, which inherently demand the highest levels of security. It acts as a pre-qualification, significantly reducing the burden of individual security assessments for each procurement. More profoundly, the certification serves as a robust third-party validation of a product's security capabilities, building profound customer trust and differentiating certified products in a competitive landscape. This transforms what might otherwise be perceived as a compliance cost into a strategic business advantage, incentivizing vendors to invest proactively in robust security features and design.
 

4.2 Ensuring Data Protection and Regulatory Compliance for Public and Private Sectors
 

KCMVP provides a robust and verifiable mechanism for information system owners to ensure that the cryptographic modules they deploy offer an acceptable and appropriate level of security for their specific applications and operational environments. This directly contributes to the protection of sensitive information. By mandating or strongly encouraging the use of validated modules, KCMVP helps government agencies and public institutions systematically mitigate significant risks associated with cryptographic vulnerabilities, unauthorized data access, and potential data breaches. The program emphasizes that non-validated cryptography is considered to provide no effective protection to information or data, effectively deeming it unprotected plaintext.  

The program establishes a consistent and high-level security baseline for cryptographic implementations across a wide array of IT systems throughout South Korea. This standardization promotes a uniform and enhanced level of data protection nationwide, reducing inconsistencies in security posture. KCMVP-certified solutions are essential for managing data security requirements in highly sensitive and critical areas, including national defense systems and Internet of Things (IoT) data protection. The case study of Dream D&S highlights how KCMVP certification is integral to providing secure solutions for these vital sectors.  

The widespread reliance of South Korean information system owners on KCMVP-validated modules implicitly demonstrates a high level of trust not only in the certification process itself but, more significantly, in the National Intelligence Service (NIS) as the ultimate validation authority. This trust is foundational for the effective functioning and acceptance of a national cybersecurity program, especially one overseen by an intelligence agency. The broad adoption and reliance on KCMVP-certified modules by government and critical infrastructure entities imply a deep-seated confidence in the NIS's rigorous, impartial, and expert assessment of cryptographic security. This confidence is paramount because, without it, agencies might resort to less secure, unvalidated solutions or attempt costly and less effective internal validations. The NIS's role as the primary intelligence agency further imbues the validation with a sense of national security imperative and authority, suggesting that KCMVP is perceived as a vital component of South Korea's national defense against cyber threats, rather than just a bureaucratic compliance exercise. This state-backed assurance is a powerful driver for adoption and trust.  

5. KCMVP in the Global Landscape: A Comparison with FIPS 140-2/CMVP

5.1 Similarities and Distinctions in Validation Methodologies

KCMVP, much like the Cryptographic Module Validation Program (CMVP) operated jointly by the U.S. and Canada, and Japan's JCMVP, shares the fundamental objective of validating cryptographic modules. The core goal across these programs is to assure the security, proper implementation, and functional correctness of cryptographic components used in sensitive information systems. Both KCMVP and JCMVP were established with ISO/IEC 19790 serving as a foundational international standard for their programs.

This indicates a common global baseline for defining cryptographic module security requirements, suggesting a shared understanding of best practices in the field. A commonality across these programs is the adoption of a multi-level security approach. Both KCMVP and CMVP (under FIPS 140-2/3) employ tiered security levels with cumulative requirements, allowing for different degrees of security assurance tailored to varying application needs and data sensitivities. All these validation programs rely on independent, accredited testing laboratories to perform the detailed technical evaluations of cryptographic modules. For CMVP, these are Cryptographic and Security Testing Laboratories (CSTLs) , while KCMVP utilizes various accredited agencies. These labs conduct the initial assessments before the central authority grants final validation. 

 
Despite these similarities, key distinctions exist. CMVP is a collaborative effort between the U.S. National Institute of Standards and Technology (NIST) and the Canadian Centre for Cyber Security (CCCS). In contrast, KCMVP is exclusively overseen by South Korea's National Intelligence Service (NIS). A significant divergence lies in the approved cryptographic algorithms. KCMVP specifies a distinct set of Korean-approved cryptographic algorithms, notably excluding widely adopted international standards like AES in favor of domestically developed ones. CMVP, conversely, validates modules against the FIPS 140-2/3 standard, which mandates the use of FIPS-approved cryptographic algorithms. CMVP has also undergone a significant transition from FIPS 140-2 to the newer FIPS 140-3 standard, ceasing to accept new FIPS 140-2 submissions after April 1, 2022. Existing FIPS 140-2 modules will be moved to a historical list after September 21, 2026, for new systems. KCMVP's recent updates, while distinct, focus on increasing its own required security strength to 128-bit from 2025.  

5.2 International Recognition and Interoperability Considerations
 

Historically, there have been instances of international cooperation and recognition among 

these programs, such as the memorandum of understanding established between Japan's JCMVP and the US/Canada's CMVP. While not explicitly stated for KCMVP, this precedent suggests a potential pathway for future cross-program recognition or collaboration.  

The distinct preference of KCMVP for domestically developed algorithms can pose challenges for international interoperability. Systems requiring secure communication across national borders might face complexities if they need to integrate with or operate alongside systems adhering to different cryptographic standards, such as FIPS-approved algorithms. This could necessitate the use of multiple cryptographic modules or complex translation layers. This difference is not merely a technical preference; it is a profound reflection of national security and industrial policy. South Korea's decision to promote domestically developed algorithms is a strategic move to build national expertise, reduce reliance on foreign technology, and potentially mitigate concerns about supply chain vulnerabilities or the insertion of backdoors by foreign entities in critical cryptographic components. The implication is that while KCMVP-certified modules are highly secure and trusted within the Korean context, their direct integration into international systems might require additional cryptographic layers or re-validation if those systems mandate adherence to FIPS or other international standards. This highlights a deliberate national choice to prioritize cryptographic sovereignty over complete global harmonization.

  
The unique characteristics of KCMVP, despite its foundational links to international standards like ISO/IEC 19790, underscore a clear national strategy prioritizing cryptographic sovereignty and the development of a robust domestic industry. This approach, while common among nations seeking control over critical security infrastructure, presents a contrast to a fully harmonized global cryptographic validation framework. Although KCMVP operates as an independent national program, the ongoing transition of CMVP from FIPS 140-2 to FIPS 140-3 could exert an indirect, yet significant, influence on KCMVP's own future development. As a major global standard evolves to address newer threats and incorporate updated cryptographic practices, KCMVP might face pressure or an impetus to consider similar upgrades to maintain its standing or facilitate broader international market acceptance or collaboration in the long term. This suggests that while KCMVP maintains its autonomy, it operates within a global ecosystem where advancements by leading programs can set benchmarks and influence national strategic considerations.  

Conclusions

The Korea Cryptographic Module Validation Program (KCMVP) is an indispensable component of South Korea's national cybersecurity strategy, serving to safeguard sensitive government and public sector information. Its robust framework, overseen by the National Intelligence Service, ensures that cryptographic modules meet stringent security requirements through a multi-level validation process and a network of accredited testing agencies. The program's commitment to continuous improvement is evident in its forthcoming online service for streamlined validation and the mandated increase to 128-bit security strength for new modules from 2025, reflecting a proactive stance against evolving cyber threats.

A defining characteristic of KCMVP is its strategic emphasis on domestically developed cryptographic algorithms, which underscores South Korea's commitment to cryptographic sovereignty and the nurturing of its indigenous security technology industry. While this approach fosters national self-reliance and control over critical security infrastructure, it also introduces considerations for international interoperability compared to globally harmonized standards like FIPS 140-3. Nevertheless, KCMVP's selective adoption of international ISO/IEC standards for testing methodologies demonstrates a pragmatic balance, leveraging global best practices where beneficial without compromising national policy on core algorithm selection.

Ultimately, KCMVP functions not merely as a regulatory compliance mechanism but as a powerful market enabler and a trusted signal of quality for vendors, driving the adoption of secure solutions across critical sectors. The widespread reliance on KCMVP-validated modules highlights a profound trust in the NIS as the ultimate validation authority, solidifying the program's role as a vital national defense against cyber threats. As the global cryptographic landscape continues to evolve, KCMVP's ongoing development and its unique blend of national focus and selective international alignment will remain crucial for South Korea's digital security resilience and its position in the broader cybersecurity domain.

5. 글로벌 비교: FIPS 140-2/CMVP와의 관계

5.1 유사점과 차이점

KCMVP는 미국·캐나다의 CMVP(FIPS 140-2/3)나 일본의 JCMVP와 유사하게 ISO/IEC 19790을 기반으로 하며, 보안등급, 독립시험기관 체계, 인증기관 중심 구조를 공유합니다.

그러나 KCMVP는 국내 알고리즘만 승인하는 전략적 자주성을 가지고 있으며, 미국 CMVP의 AES 중심 정책과 차별화됩니다. 또한 미국은 FIPS 140-3로 이행 중이며, 한국은 2025년 128비트로 상향 예정입니다.

5.2 국제적 호환성과 인정 가능성
KCMVP는 ISO 표준을 일부 수용하지만, FIPS 및 CMVP와의 직접적인 상호인증은 없습니다. 이는 암호 주권을 지키려는 정책이지만, 국제 협력 시 추가 검증 단계가 요구될 수 있습니다.
다만, 일본 JCMVP와 CMVP 간 상호인정 사례를 감안할 때, 향후 KCMVP도 유사한 협력 가능성을 탐색할 여지는 있습니다.

KCMVP는 단순한 보안 검증 제도를 넘어, 대한민국 사이버안보의 핵심 방어 체계로 기능하고 있습니다. 국가정보원의 엄격한 감독 하에 체계적인 인증 프로세스와 전문 시험기관이 조화를 이루며, 공공 및 민간 영역 전반의 보안 수준을 획기적으로 향상시키고 있습니다.

국산 알고리즘 중심의 자주적 정책은 기술주권 확보에 기여하며, 2025년부터의 128비트 강화 조치는 미래의 위협에 선제적으로 대응하기 위한 전략적 조치입니다.

KCMVP는 단순한 규제가 아닌, 신뢰의 신호, 시장 진입의 열쇠, 국가안보의 보루로 작동하며, 앞으로도 글로벌 암호 표준의 변화 속에서도 국가 독자성과 국제 기술 기준 간 균형을 통해 대한민국의 디지털 안보를 지속적으로 지탱할 것입니다.
