DSCT: A Damage Strategy for Inter-domain Routing System Considering Cost and Based on TOPSIS

Abstract

Although the inter-domain routing system is convenient for people to communicate on the Internet, it also has some security threats. Predicting the damage strategy of the inter-domain routing system in time can protect the critical autonomous systems in the network. Under the premise of considering the attack cost, this paper proposes a damage strategy for inter-domain routing systems considering cost and based on TOPSIS. Firstly, the attack cost associated with degree nonlinearity is defined. Then the number of link loads connected to the node and the number of reachable nodes are proposed. And finally, a sequence of node attack is calculated by the TOPSIS method. In the two inter-domain routing networks, compared with the existing three methods. The experimental results show that the average attack cost of DSCT is at least 36.96% lower than that of other strategies when the same degree of network destruction is carried out. DSCT can damage the inter-domain routing system to the greatest extent and is the most cost-effective strategy among the four methods.
