Using Protocol Composition Logic (PCL),this paper proves a Mobile IP (MIP) registration protocol that is based on certificateless public key signature without pairing between home agent and foreign agent,which minimizes the registration time and cost as well as improves the security compared with the identity-based and certificate-based registration protocol. Analysis and proof shows that the proposed protocol provides users security and authentications,moreover,the anonymity property is proved correct.展开更多
