摘要
Ad hoc网络的自组织性是其最大的优点。这种自组织性和无中心性给密钥管理带来了很大的难度。论文在将网络划分为簇的基础上,利用基于椭圆曲线的分布式密钥产生算法,提出了一种基于信任值的密钥管理方案,能够选取出合适的簇首担任CA服务器,实现了完全自组织的分布式密钥管理。
The character of self-organization is the most significant advantage ofAd hoc networks. However, this character and its lack of any centralized control bring big challenges to its key management. Based on the clustering of the networks and the distributed key generation arithmetic based on elliptic curve, this paper proposes a trust value based key management scheme, which can choose the most suitable nodes as the cluster-heads and can realize the fully self-organization distributed key management.
