CoISM: Improving Security and Accuracy of BGP through Information Sharing

Ensuring the authenticity of BGP routing information is a challenge problem of Inter-domain routing security. Due to lack of global information view, is it difficult to single autonomous system to detect bogus BGP routing information. A method for cooperative BGP validation based on self-organizing information sharing is presented in this paper. Cooperative validation gives a more comprehensive route view by sharing information among autonomous systems. It loosens the constraints from the autonomy and improves the security and accuracy of BGP. By leveraging the characteristics of locality and relativity, which is caused by routing policy, cooperative validation drives autonomous systems to cooperate independently and share information on-demand. More specifically, our method has incentive effect and supports incremental deployment.
