According to the characteristics of group communication in mobile Ad hoc networks,this paper proposed a distributed key management scheme based on group signature authentication.By adopting the threshold cryptography and the method of third-party signature authentication,this scheme enhanced the authentication reliability and reduced largely the authentication cost in key agreement process greatly.The analysis shows this scheme is provably secure against the active and passive attacks with fault-torrance,achieves the trust level 3,has perfect forward and backward secrecy,and reduces the cost of computation and communication greatly.
