摘　　要：可传递签名是由Micali和Rivest在2002年首先提出的,主要用于对二元传递关系进行签名。本文综述了可传递签名的研究现状,描述了可传递签名的定义、模型及其安全性,概括了现有的可传递签名方案,包括无向传递签名方案和有向传递签名方案。最后对可传递签名的研究前景进行了展望。Transitive signature was first introduced by Micali and Rivest in 2002 to meet the need of certain applications like signing a chain of command, a chain of Certificate or transitive binary relations. In this paper, research actuality of transitive signatures is presented. The definition, the security and a model of transitive signatures are described. Two classes of transitive signature schemes, which are undirected transitive signature schemes and directed transitive signature schemes, are also described in details. Finally, some related problems about transitive Signatures are summarized.
