Food and discussion begins at 12:30 pm. Everyone invited.

Traditionally, web browsers decide to trust public keys a specific domain on the web if they are presented with a certificate signed by any of a large number of CAs a large number of CAs built into the browser. This has long been unsatisfactory to the security community and several recent high-profile CA compromises have motivated new thinking in this area. This talk will survey recent work in the area, framing the problem as one of reliably delivering authentic security policies for each domain to the browser. The talk will provide a broad survey of recent proposals such as Certificate Transparency, Sovereign Keys, TACK, Accountable Key Infrastructure, S-links, DNSSEC/DANE, and NameCoin.
