Efficient and secure certificateless authentication and key agreement protocol for hybrid P2P network

In order to ensure authentication and confidentiality of E-Commerce and other applications in the P2P network, a new secure certificateless authentication and key agreement protocol is proposed. In this paper, it shows the new protocol is so suitable in one domain and across domain that it is fit for the hybrid P2P network. Security analysis shows that it achieves almost known security attributes, such as implicit key authentication, perfect forward secrecy, known-key secrecy, key-compromise impersonation, unknown key-share resilience, known session-specific temporary information security and no key control. Moreover, our proposed protocol is of great practical and efficiency for the hybrid P2P network.
