摘要： 提出一种有效的基于椭圆曲线的(t, n)门限密钥管理方案EECTKM。该方案将证书机关(CA)分布到一个Server组，并动态维护网络中一定数量的Server节点，同时考虑公钥证书服务负载的合理分担，具有安全性高、计算量小、公钥证书服务负载均衡等特点。仿真结果表明，EECTKM能够有效地提高公钥证书服务的效率，同时具有较强的容忍Server节点失效的能力。

Abstract: An efficient (t, n) threshold key management scheme for Ad Hoc networks (EECTKM) is presented based on elliptic curve. In the scheme, the certificate authority (CA) is distributed to a group of server nodes. EECTKM can balance the loads of services of server nodes and maintain a certain number of server nodes in network dynamically. It has characteristics of high security, less computational cost, balanced service loads of Server nodes etc. Simulation results show that EECTKM can enhance the efficiency of public key certificate services and has good ability to tolerate failure of server nodes.
