BGP security was a hot topic a few years ago, but is not as much studied these years. However, with technologies such as IPv6 and DNSSEC, BGP security is making a comeback, especially in the industry. We academics also have much to contribute in this space. In today’s Three Paper Thursday, I will highlight three recent work related to BGP security. It is also a good starting point to catch up in BGP security for those whose last memories of BGP security involve proposals such as S-BGP and SoBGP.
