摘　　要：将隐式认证技术与密钥调和技术相结合,设计出一种强安全认证密钥交换协议。该协议具有较高的效率以及较小的通信带宽,满足弱完善前向安全性。基于环上带误差学习难题假设,该协议在扩展Canetti-Krawczyk模型下可证明安全。A strongly secure authenticated key exchange protocol is designed by combining implicit authentication with key reconciliation. The protocol has high efficiency and small communication bandwidth,which satisfies weak perfect forward secrecy. Based on the hardness of the ring learning with errors problem, this protocol can be proved to be secure within theextended Canetti-Krawczyk model.
