摘要
基于PGP的"信任关系"理论,利用(t,n)门限秘密共享体制,提出一种Ad hoc网络自组织密钥管理方案的新节点加入安全算法。该算法通过对新节点的多点信任认证以及对身份标识的一致性、唯一性判断,保证了Ad hoc网络中新节点的安全性,并健全了自组织的密钥管理方案。仿真结果表明,这一算法在对新节点安全认证的同时保证了认证的成功率,由此提高了网络的安全性。
Based on the "Trust Relationship" of PGP, a secure algorithm for affiliating new nodes of selforganized 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 hoe 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.
