移动自组网是一种新型的移动网络,它的无中心、无基础设施等特性决定了在这种网络中提供证书服务必须采用分布式的体系结构。现有的分布式认证技术是基于(n,t)门限方案的单层结构,当一个节点的单跳邻居节点数目小于系统门限值时就无法正常工作。该文结合Feldman可验证秘密共享策略提出了一种多层分布式认证技术,一方面可以解决单层分布式认证技术中邻居节点数目不足问题,另一方面可以在证书签名合成中验证私钥分量正确性,保护系统私钥不泄漏。
Mobile ad hoc network (MANET) is a new type of mobile network. Its non-center and infrastructure-less features determine that a distributed architecture must be used to provide certificate services in such a network. The existing distributed authentication technology is a single-layer structure based on the (n, t) threshold scheme. When the number of single-hop neighbors of a node is less than the system threshold, it can not work normally. This paper presents a multi-layer distributed authentication technology based on the Feldman verifiable secret sharing strategy. On the one hand, it can solve the problem of insufficient number of neighbor nodes in the single-layer distributed authentication technology; on the other hand, it can verify the private key component Correct, protect the system private key does not leak.
