Google Researchers Propose Plan To Fix CA System

Trailrunner7 writes "The security industry has no shortage of hard problems to solve, but the one getting the most attention right now is finding a way to improve, or ideally, replace, the CA infrastructure. The latest in what has become a series of recent proposals to help shore up the certificate authority system comes from a pair of Google security researchers who have laid out a plan for providing auditable public logs of certificates as well as proofs for each certificate issued. The system proposed by Google's Adam Langley and Ben Laurie (PDF) comprises three separate ideas, but relies on the creation of a publicly viewable log of every public certificate that's issued by a CA. There could be any number of public logs of these certificates, but the logs will be structured so that they are append-only. The entries in the logs will be the end certificates in the issuance chain. In addition to the logs, the proposal includes the use of proofs that are sent with each certificate to the user's browser. Laurie and Langley haven't defined exactly what the proof would look like, but suggest that it could be an extra certificate or a TLS extension."

    Solve that problem via DNSSEC. Publish your self signed key via DNS, and at least someone connecting knows that the server they are talking to currently owns the domain name and the connection is encrypted end-to-end, which is all that CA certs seem to have devolved to.
