A Tripartite Key Agreement Protocol of Authentication
Tang Peng-zhi
The new agreement proposed a safe and effective tripartite key exchange protocol,through assumptions in CDH,using elliptic curve cryptosystem keystore and temporary long-term keystore mixed method to assure the security,through the agreement the safety of this agreement are analyzed,show that this agreement can resist many attack;On the other hand,any of the parties involved two sides as a group,generates a common key,then both sides of arbitrary party with third parties again authentication and key agreement,news that need only five times information interaction can achieve the whole agreement of mutual authentication and key confirmation function,but through the comparison also show that agreement has high efficiency.
