The security of inter-domain routing system greatly depends on the trustworthiness of routing information and routing behavior of autonomous system (AS). Many researches on e-commerce, grid, and p2p have proven that reputation mechanism is helpful to inhibit the spread of false route and the occurrence of malicious routing behavior. To increase AS resistance to malicious routing attack, we designs an alliance based reputation model for AS routing behavior trust evaluation. Our approach calculates AS reputation with the Bayesian probability model and manages AS reputation with AS alliance. Compared with the fully distributed reputation model, our model has lower storage and communication overhead. This reputation model is incremental deployment and easy to implement. It can be employed for securing AS routing and assisting malicious behavior detection.
