摘　　要：公钥密码体制的思想是密码史上一个重要的里程碑。本文详细的介绍了公钥密码体制的研究发展及实现应用,其中着重讨论了目前已有的几个比较重要的、有代表性的公钥密码体制如RSA、ECC、XTR的攻击现状,介绍了它们长期的安全性、标准化及其实现状况。最后我们简单的介绍了最近所提出的一些公钥密码体制如基于辫群的密码体制,量子公钥密码体制等。The advent of public key cryptography is a milestone in the development of modern cryptography. A survey of the research and implementation of PKC is presented in this paper, with the emphasis on the attack status of some typical systems such as RS A, ECC and XTR, and also their secure properties, standardization and realization being introduced in detail. Finally, some newly presented public key systems, such as public key cryptosystem based on braid group and quantum cryptosystem, are briefly introduced.
