Description

technical field [0001] The invention relates to a routing protocol reinforcement method based on a trusted cryptographic card. Background technique [0002] With the rapid expansion of the Internet, coupled with the characteristics of heterogeneity, dynamics, and deception in the complex network environment, the problem of network information security has become increasingly prominent. As an important network component node, routing devices provide the interconnection mechanism of heterogeneous networks. Routing protocols share routing information between routing devices and select the best path between them and other routing devices according to topology information. Its importance lies in It is self-evident in the entire communication network. However, at the beginning of the design of the routing protocol, each node is considered to be credible. The routing protocol itself has many security flaws, and the current security measures focus on business data encryption. There...

Problems solved by technology

By sorting out the current public literature and technical materials, we can find that the security protection of routing protocols at home and abroad mainly focuses on two strategies. One is to increase security measures for specific routing protocols. The research ideas and research methods are still aimed at the routing protocols themselves. To repair and improve the discovered security loopholes, it is necessary to modify the specific protocol content, the method is relatively complicated, and there are hidden dangers of introducing new security issues; the second is to add a trust management system (TMS) in the network, and verify the route through the interaction between the routing device and the TMS. The reliability of the protocol data source and the integrity of the routing protocol data, this strategy relies on the interaction between the routing device and the TMS, the TMS becomes the bottleneck of the entire network expansion, and increases the maintenance cost of the network
