Aiming at the security of authentication protocol for heterogeneous wireless network

a mutual authentication and key agreement protocol

which was based on CPK algorithm and improved ECDH algorithm

was proposed.The temporary authentication identity and temporary communication identity was adopted to realize user identity anonymity.The ordered pair of temporary communication identity was proposed to prevent replay attack in the process of re-authentication.The risk of key compromise was also avoided in the proposed protocol.By security analysis

this protocol had the security properties such as identity authentication

key security and anonymity.
