摘要
采用具有超大规模密钥管理优势的组合公钥密码体制,结合Shamir的(t,n)门限方案思想,提出了一种适用于移动自组网环境的部分分布式密钥管理方案,给出了一种服务节点私钥矩阵份额的更新方法,并对方案的公私钥种子钥矩阵生成进行了实现。分析表明,该方案具有高的安全性、小的计算量、强的扩展性和好的实用性,适用于移动自组网环境。
This paper proposed a partly distributed key management scheme for mobile Ad hoc network(MANETS),which was combined public key(CPK) cryptography with Shamir(t,n) secret sharing scheme.Designed a method to update the private key shares of service nodes.And gave the process of generating public/private key seed matrix.Analysis shows that this project is secure,distensible,concise,practical and applicable for the characteristics of MANETS.
