摘要
在部分分布式CA模型的基础上,结合门限秘密分享机制和双线性对密码体制,提出了一种新的部分分布式的密钥管理方案。本方案通过路由机制来维护一个特殊的服务器组,使认证请求可以被就近的服务器节点快速响应。仿真结果表明,与无路由的普通方案相比,本方案提高了认证成功率,缩短了证书更新时延,保证了Ad Hoc网络的可用性和安全性。
On the basis of the partial distributed CA model,and combined the threshold secret sharing and bilinear pairings,a new partial distributed key management scheme in Ad Hoc network was proposed.The scheme through routing maintains a special server group to make the certification request be responded fast.Simulation results show that compared with the ordinary scheme without routing,the new scheme boosted the success rate of certification,shorten certification update delay,and improved the availability and security of the Ad Hoc network.
