Secure Algorithm for Affiliating New Nodes of Self-organized Key Management Scheme in Ad hoc Network

Based on the "Trust Relationship" of PGP,a secure algorithm for affiliating new nodes of self-organized key management scheme in Ad hot network is proposed by using the(t,n) threshold secret sharing scheme. Because of the multi-authentication for new nodes and the judgment of the identification of consistency and uniqueness,the security of the new nodes in Ad hoc network is ensured and the self-organized key management scheme is improved.Simulated results show that the successful rate of authentication is ensured while the new nodes are authenticated securitily,thus improving the security of the network.
