信息理论密码学的新进展及研究问题

Recent Development and Research Problems of Information Theoretic Cryptography

本文用信息论观点对信息理论密码学的新进展及若干未解决的研究问题作综述，其中也包括作者的某些研究工作内容包括近年来在Shannon的密码系统和若干不同于Shnnon模型的新密码系统方面基于信息论的研究结果和公开问题以及对信息理论密码学今后发展的展望．

This paper gives a survey for the recent development and research problems of information theoretic cryyptography . The content includes recent results and open problems on cryptosystems of Shannon's model and of new models hased on infonnation theory, some research work of the authors is also included. In the end, a brief discussion on the prospect of information theoretic eryptography in the future is given.
