摘要：As a fundamental cryptography primitive, group key agreement protocol aims at allowing participants to establish a common secret key through open networks. At present, it has become a hot issue in the field of multi-party cryptography. The security goal and formal security model of the group key agreement protocol are introduced. Besides, the state of group key agreement protocol is analyzed and some problems for further research are discussed.
