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.
