Survey of Secure Group Communication Based on Secret Sharing Theory
基于秘密共享理论的安全组通信研究综述*

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.
