摘要
公钥密码学是保障现代通信安全与数据安全的重要基础技术。介绍了当前量子计算发展对公钥密码学造成的威胁,以及密码标准化组织和密码学研究的应对措施,依据所使用的基础数学困难问题分类阐述基于格、编码、多变量、哈希函数、曲线同源的后量子密码及其优劣势等特点。以当前后量子密码标准进展为主线,从算法安全性分析、后量子迁移的技术路线、与量子通信技术结合、新的数学困难问题探索等方面提出后量子密码学的发展方向建议。
Public key cryptography is a significant and fundamental technique to ensure security of modern communication and data.This paper introduces the threat to public key cryptography posed by the current development of quantum computing and the countermeasures of cryptography standardization organizations and cryptography community,and then according to the basic mathematical difficult problems used,elaborates the characteristics of post-quantum cryptography based on lattice,encoding,multivariate equations, hash function, curve isogeny and their advantages and disadvantages in categories.Based on the present progress of post-quantum cryptography standardization, this paper puts forward thedevelopment direction of post-quantum cryptography from the aspects of algorithm security analysis,technical route of post-quantum migration, combination with quantum communication technology, andexploration of new difficult mathematical problems.
