A new method based on certificateless authenticated key agreement protocols
Jun Ma
Abstract
The tripartite key agreement protocol that Joux has proposed is more efficient and simple,but it is vulnerable to man-in-the-middle attack.A new method based on certificateless authenticated key agreement protocols is proposed,which extends tripartite key agreement to multi-party accompanied by its authentication function.It has a lot of advantages,such as a short signature,high calculation efficiency,simple management about certificate and escrow-free anonymous key.The new method enjoys much secure prosperity,for instance,which has a non-key control and forward security,resists man-in-themiddle and leaked disguise attack,and so on.
