Today, with the rapid development of information technology, cyber security has become the focus of global attention. With the continuous progress of quantum computing technology, communication security under the traditional cryptographic algorithm system is facing unprecedented challenges. According to Xinhua News Agency, the proposal submitted by Chinese experts at the ISO/IEC JTC1/SC6 meeting held in Stockholm, Sweden, was recently adopted, which not only marks China's growing influence and leadership in the field of global cybersecurity, but also indicates that the global data communication system will transition more smoothly from the era of traditional cryptographic algorithms to the era of post-quantum cryptographic algorithms.
Proposals by Chinese experts and international cooperation
At this meeting, the proposal of Chinese experts on the design of a communication network security protocol resistant to quantum attacks was unanimously approved by the participants. This achievement not only demonstrates China's technological strength and innovation capabilities in the field of cybersecurity, but also reflects the international community's recognition of China's technological solutions. The meeting decided to set up a preparatory work project, with Chinese experts leading the development of protocol design guidelines, which will be an important opportunity for China to play a greater role in global cybersecurity governance.
Challenges and solutions to quantum computing
The development of quantum computing has brought subversive challenges to existing communication network security protocols. The superior computing power of quantum computers can theoretically easily crack the existing public-key key system, which poses a huge threat to the security of global communication systems. According to IT House, attackers have begun to collect and store important data in preparation for cracking it with quantum computers in the future. Therefore, the development of communication network security protocols resistant to quantum attacks has become an urgent task in the field of global network security.

Technical details and innovations of the proposal
The core of the quantum-resistant communication network security protocol proposed by Chinese experts lies in the development of a set of encryption technologies that can resist quantum computer attacks. The threat of quantum computers mainly comes from their ability to crack traditional encryption algorithms, especially public-key cryptography systems, such as the RSA algorithm, which relies on the factorization of large integers, and quantum computers can efficiently solve this problem.
Post-Quantum Cryptography (PQC)：The proposal could involve post-quantum cryptography algorithms, which are cryptographic algorithms designed to resist attacks by quantum computers. These algorithms include different types of cryptosystems such as lattice-based, multivariate, hash-based, and code-based.
1. Key exchange protocols: In the quantum era, secure key exchange protocols have become particularly important. The new protocol may include the use of quantum key distribution (QKD) technology, a method that uses the principles of quantum mechanics to securely distribute keys that remain secure even in front of quantum computers.
2. Digital signature algorithms: To ensure data integrity and non-repudiation, new protocols may include quantum-resistant digital signature algorithms. These algorithms ensure that the verification of signatures remains secure and reliable even in the face of quantum attacks.
3. Quantum random number generation: New protocols may take advantage of quantum randomness to enhance the security of random number generation, which is critical for cryptographic key generation.
The proposal also addresses the following innovative features:
1. Integrating traditional and quantum technologies: Chinese experts' proposals may include innovative solutions that combine traditional and quantum cryptography to achieve a smooth transition to existing infrastructure.
2. Balance between performance and security: When designing new communications network security protocols, Chinese experts may pay particular attention to the balance of performance and security to ensure that the new protocols protect communications without much impact on network speed and efficiency.
3. Global Standards: This project, led by Chinese experts, is expected to promote the formation of a global unified network security standard for quantum-resistant communications, which is of great significance for global cybersecurity.

Editor's point of view
China's proposal is undoubtedly an important milestone in the current global cybersecurity landscape. It not only demonstrates China's technological progress in the field of cybersecurity, but also shows China's determination to assume global cybersecurity responsibilities. In the context of the increasing maturity of quantum computing technology, traditional encryption methods, such as RSA and ECC, will no longer be secure. Quantum computers can easily solve problems that are difficult for traditional computers to solve, such as large integer factorization, which poses a direct threat to existing encryption systems.
It is estimated that once quantum computers become a reality, the currently widely used encryption algorithms will become vulnerable, and global cybersecurity will face a reshuffle. Therefore, the proposal of the anti-quantum attack communication network security protocol put forward by Chinese experts is not only a supplement to the existing network security system, but also a revolution for the future network security system.
In addition, China's proposal also reflects China's active role in global cybersecurity governance. In the field of global cybersecurity, China is moving from being a rule-follower to a rule-maker. This shift will not only help enhance China's influence on the global stage, but also contribute Chinese wisdom and solutions to global cybersecurity governance.
In the global cybersecurity space, collaboration is key. China's proposal has been widely recognized by the international community, which shows that the international community is willing to cooperate with China to jointly address challenges in the face of common cybersecurity threats. This spirit of cooperation is the cornerstone of global cybersecurity governance and a prerequisite for building a more secure and stable cyberspace.
In short, the global cybersecurity agreement promoted by Chinese experts is not only a breakthrough at the technical level, but also an important progress in global cybersecurity governance. With the continuous development of quantum computing technology, this protocol will play an increasingly important role in the field of global cybersecurity. We look forward to China playing a greater leading role in global cyber security and contributing more to building a safer and more stable cyberspace.
