一种高效的匿名口令认证密钥交换协议
An Efficient Anonymous Password-based Authenticated Key Exchange Protocol
摘要
Abstract
According to the problem of protecting users' privacy in the new applications of network such as cloud computing,an anonymous password-based authenticated key exchange(APAKE)protocol based on CDH assumption of elliptic curve cryptography is proposed,in which a client can establish a shared session key with the server authentically and anonymously.The system model,security model and formal proofs illustrate that the proposed APAKE protocol satisfies three properties: correctness,PAKE security and user's privacy.Based on the analyzes with the existing APAKE protocols,it is shown that the protocol is secure against impersonating attack and off-line dictionary attack,and provides mutual authentication; and the new construction is more efficient than others' APAKE protocols.关键词
