In order to make key agreement protocol to resist against the active attacks, proposed a certificateless authenticated tripartite key agreement protocol. First, analysed the existing key agreement protocol. Then designed a security tripartite key agreement scheme based on the theory of certificateless cryptography. This protocol builds a security tripartite session key only need one round message exchange, which can strongly overcome the key escrow and offer perfect forward secrecy. The analysis of security and complexity shows that this protocol is secure and effective.
