摘　　要：针对天地一体化网络节点的高速移动和频繁跨域问题,该文基于公钥基础设施框架设计了一套移动认证协议。该协议以公钥密码算法为基础,实现了相邻节点间的匿名认证;利用门限理论将私钥分量分配给n个节点,实现多节点协作认证和权限的动态回收;结合分布式认证与链式认证,实现了分布式的公钥基础设计,为节点高速移动提供了认证基础。该协议体系无中心、自适应、可追踪,符合天地一体化网络的无中心和节点对等等特性。实验表明,与传统的分布式认证相比,该体系具有更强的认证成功率和安全性。In order to solve the problem of the nodes with a high-speed move and frequent cross-domain in the space-earth integration network nodes,the mobile authentication protocol based on public key infrastructure（PKI） is proposed.Based on the Rivest Shamir Hellman（RSA） algorithm,the protocol realizes the anonymous authentication between neighboring nodes.It distributes the private key components to n nodes according to the threshold theory,and then realizes the multi-node collaboration certification and dynamic permission-recovery.In addition,combining with distributed authentication and chain certification,the protocol achieves distributed PKI and provides certification basis for high-speed move.This protocol frame,which is decentralized,self-adaptive and traceable,can fulfill the quality of the space-earth integration network.Experiments show that the success rate and safety of the system is much better than the traditional distributed certification protocol.
