摘要：Recently, the notion of asymmetric group key agreement (ASGKA) was introduced, in which the group members merely negotiate a common encryption key which is accessible to any entity, but they hold respective secret decryption keys. In this paper, we propose an ASGKA protocol with traitor traceability. The new scheme achieves most of known security attributes, such as session key secrecy, knownkey secrecy and forward secrecy. In addition, the protocol can provide traitor traceability. © 2010 IEEE.
