Working Group 6: Secure BGP Deployment December 16, 2011 Andy Ogielski, Renesys Jennifer Rexford, Princeton U. WG 6 Co-Chairs

2 Working Group 6: Secure BGP Deployment  Short Description: The Border Gateway Protocol (BGP) controls inter-domain packet traffic routing on the entire global Internet. BGP relies on trust among operators of gateway routers to ensure the integrity of the Internet routing infrastructure. Over the years, this trust has been compromised on a number of occasions, revealing fundamental weaknesses of this critical infrastructure. This Working Group will recommend the framework for industry regarding incremental adoption of secure routing procedures and protocols based on existing work in industry and research. The framework will include specific technical procedures and protocols. The framework will be proposed in a way suitable for opt-in by large Internet Service Providers (ISPs) in order to create incentives for a wider scale, incremental ISP deployment of secure BGP protocols and practices in a market-driven, cost-effective manner.  Duration: August 2011 – March 2013
