基于秘密共享理论的安全组通信研究综述

Survey of Secure Group Communication Based on Secret Sharing Theory

秘密共享是密码学中的一个新课题,随着对其理论的不断研究,秘密共享方案越来越多地被应用到安全通信中,特别是在安全组通信中的应用使得通信的保密性、鲁棒性、完整性以及通信效率都得到了很大的提高。从秘密共享的基本理论出发,着重介绍了秘密共享在门限密码系统、组密钥管理、密钥托管、数字签名和认证以及分布式容侵系统中的应用,并且提出了秘密共享理论及其应用的发展趋势,为今后进一步的研究指明了方向。

Secret sharing is one of the new subjects of cryptography. As the theory of secret sharing developed, it is used in secure group communication more and more regularly. It enhanced the security, robust, integrity and the efficiency of communication. In this article, the theory of secret sharing is first showed, then its applications in threshold schemes, group communication, key escrow, digital authentication and intrusion tolerance system are introduced. At last, the direction of future research is proposed.
