【Abstract】 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.更多还原
