摘　　要：公钥密码是信息保密工作中重要的发展形势,从数学角度讲,公钥密码是一种单向的函数形式,相当于给每个人都配备了一把私人密钥,而每个人除了私人密钥外还有一把公共密钥,公共密钥是公共的,可以将信息发送给任何人,但是如果将信息加密以后,只有使用私人密钥才能将信息打开.这种抗泄漏的公钥密码体制在密码体制发展中属于一种里程碑式的改革.文章主要对抗泄漏公钥密码体制的相关问题进行研究,分别从大整数分解困难问题公钥密码体制、离散对数困难问题公钥密码体制以及其他一些近些年发展起来的新型公钥体制进行阐述,以期为抗泄漏公钥密码体制的研究提供理论依据.Public key cryptography is an important development form in the information secrecy work.Mathematically,public key cryptography is a one-way form of function that is equivalent to giving everyone a private key,and each person has a public secret key in addition to a private key.The public secret key is public,which can send information to anyone.However,if the information is encrypted,it can only be opened using a private secret key.This leak-resistant public-key cryptosystem is a landmark reform in the development of cryptographic systems.The paper mainly studies the problems related to the public key cryptosystem,including the large integer decomposition problem,the discrete logarithm problem,and some other new public key systems developed in recent years are described in order to provide a theoretical basis for the research of anti-leakage public key cryptosystems.
