Forward secure key agreement protocol based on signcryption
一个前向安全的基于签密的密钥协商协议*

Secure and efficient message delivery is one of the major aims of computer and communication security research. Based on the key agreement protocols using signcryption proposed by Zheng and Zhang chuan-rong, this paper proposed a forward secure key agreement protocol based on identity-signcyption. It combined the advantages of the identity-based public key system and signcryption technique. As compared to the existing schemes, the protocol is not only confidential, authenticated, but also forward secure.
