摘　　要：量子算法的提出,使得传统的密码体制在量子计算下不再安全。基于编码的加密方案具有抗量子攻击特性,引起密码学界广泛关注。许多密码学者对基于编码的加密方案进行深入研究,在研究过程中,人们对其加密方案的优势和缺点逐渐有了深刻的认识。目前,基于编码的密码体制已成为后量子密码学最有前途的方案之一。综述了基于编码加密体制的发展现状,阐述了现有基于编码的加密体制和目前已知存在的攻击,并指明了未来具有潜力的发展方向。The quantum algorithm which was put forward recently has led to great insecurity of cryptographic analysis of the coding under quantum computing.The future of the code-based cryptography with anti-quantum attack properties was questioned by many people.However,in the research process,people gradually had a deep understanding of the advantages and disadvantages of its encryption scheme.At present,the code-based cryptography has become one of the most promising post-quantum cryptography schemes.The code-based encryption schemes were summarized and the existing attacks of their original schemes were analyzed.Finally,the nature of the security problem of encoding-based encryption system is analyzed,and the future development direction is expounded.
