Distributed CA for Mobile Ad hoc Networks
分布式CA在移动自组网中的应用

In this paper, we proposed a Security Framework of Distributed CA for Manet(Mobile Ad hoc Networks). The key elements of the framework are: distributed CA based on threshold cryptosystem which can provide a highly secure and highly available.The application of Elliptic Curve Cryptography (ECC) which is appropriate for mobile nodes with limited computational power.A scheme for dynamically partitioning the network into smaller clusters of nodes based on nodal mobility which can reduce the storage of node.A scheme for election based on the resource which can improve the efficiency of distributed signature and be favor of the system load balance of the usage of device resorce.
