一种基于公钥算法的 ISIS 认证机制

摘要

Secure routing information exchange depends on the routing information authentication mechanism. Here,the pa⁃per proposes a routing information authentication mechanism for ISIS based on public key algorithm and analyzes the results of the network performance. Compared with the traditional authentication method,the algorithm has higher security. However, when there are more nodes in the network,the network convergence time is increased.%　　安全的路由信息交换依赖于路由信息认证机制，为了提高路由信息认证机制的安全性，基于公钥算法，给出一种用于 ISIS 的路由信息认证机制。通过对算法性能进行分析，与传统的路由信息认证方式相比，该算法具有更高的安全性，但在网络节点较多的情况下，网络收敛时间较长。
