In traditional networks ,the authentication is performed by certificate authoritys(CA),which can’t be built in distributed mobile Ad Hoc Networks however. In this paper, we propose a fully self-organized public key management based on bidirectional trust model without any centralized authority that allows users to generate their public-private key pairs, to issue certificates, and the trust relation spreads rationally according to the truly human relations. In contrast with the traditional self-organized public-key management, the average certificates paths get more short,the authentication passing rate gets more high and the most important is that the bidirectional trust based model satisfys the trust requirement of hosts better.
