摘要

IKEv2 is the new version of Internet Key Exchange protocol. Despite of its several advantages, it is still susceptible to some attacks, such as man-in-the-middle attack and replay attack. In this paper, we extend BSW logic (E-BSW) first, and provide the formal semantics for validating the inference rules. Then we analyze IKEv2 protocol formally, propose an improved scheme, and prove it by the EBSW logic. The improvement can resist man-in-themiddle attack and replay attack, and fulfill the authentication, secrecy and integrity of this protocol.
