在路由信息协议(RIP)中,RIP报文都以明文的方式进行数据传输,存在被窃听、篡改和伪造的可能。为进一步提高RIP协议路由信息交换的安全性,基于量子通信的基本原理提出了 自适应量子RIP算法,实现了自治系统内路由信息的有效、安全、快速更新,并尽可能地降低了纠缠资源的消耗。仿真结果表明：与经典量子RIP算法相比, 当每一个路由器直接相连网络的数量较多,或自治系统内路由器规模增大时,提出算法能以较少的纠缠粒子资源消耗有效实现路由器路由表的自动更新。 结果表明提出算法能更好地实现RIP路由信息的安全传输。

In routing information protocal (RIP) packet, RIP messages are transmitted by the plain-text way, so it is possible to be eavesdropped, tampered and forged. In order to further improve the security of routing information exchange in RIP, an adaptive quantum RIP algorithm is proposed based on the basic principle of quantum communication. It realizes the effective, safe and fast update of the routing information in autonomous system, and reduces the consumption of entanglement resources as much as possible. Simulation results show that compared with the classical quantum RIP algorithm, the proposed algorithm can efficiently realize the routing table automatic update of router with resource consumption of less entanglement particles, when the network number directly connected to router is larger, or the router number in autonomous system is larger. Results show that the proposed algorithm can better achieve the secure transmission of RIP routing information.
