Google Bans Symantec Root Certificates

An anonymous reader writes: After in September Google discovered SSL certificates issued in its name by Symantec, and after in October the company discovered over 2,500 more certificates issued for non-existent domains, also by Symantec, Google has now decided to ban Symantec's dodgy certificates from Android and Chrome. "Symantec has decided that this root will no longer comply with the CA/Browser Forum's Baseline Requirements," said Ryan Sleevi, Google Software Engineer. "As these requirements reflect industry best practice and are the foundation for publicly trusted certificates, the failure to comply with these represents an unacceptable risk to users of Google products." Apparently Symantec hasn't been very careful of where and to whom it issues SSL certificates from a particular root branch.

      The benefit comes when everyone does it all the time. All traffic is encrypted and integrity checked thusly. Yes it is vulnerable to MITM on initial use, but it raises the bar for intelligence agencies because they now have to MITM everything, all the time to have a hope of pulling off a targeted attack later. Their bulk data browsing becomes fairly pointless. Instead they have to perform bulk MITMing.

      Part of the dynamic here is that the PKI is so fragile that TOFU simply works better. It fails less often than TLS, which fails completely when a single CA misbehaves. TOFU isn't by any means perfect, but it's better than TLS and X.509 PKIs. It would be nice to have a PKI that works, but we don't.

      The middle ground I would like to get to is
      1) Everything establishes session keys on first use and key continuity, all the time. If there's identity authentication as well, then great, but don't make it requirement that gets in the way of running a link cipher.

      2) Identity authentication can happen before, at the time of or after first use.

      This way hardware and software can be built that encrypts by default without user involvement or understanding. Identity verification can be post-hoc applied if necessary and applied beforehand when it matters or people care enough.

      Cite? I seriously doubt that TOFU would actually work better if it were used on a large scale (SSH is *not* large scale). Key rotation is particularly problematic; by default TOFU just says "no" to key rotation, which is also bad. PKI + TOFU has interesting properties, but key rotation is still a problem.

      IMO, what would be best is PKI + Certificate Transparency + Convergence + (limited) TOFU. Marlinspike touts Convergence as an alternative to PKI, but I think it would work better as an additional layer. PKI works beautifully in the common case where CAs behave correctly and don't lose their keys. Adding Certificate Transparency covers the poor key management case (and would have identified these Symantec problems immediately), and Convergence provides further defense against MITM attacks. CT and Convergence server certs should be pinned, of course.

      And note that in most cases there's no reason your browser needs to delay the connection while it checks the additional layers. It can go ahead and establish the connection and begin downloading content while it checks with the CT and Convergence servers. It probably should defer rendering until it completes the additional checks, to protect against malicious content... unless it has already visited this site, and seen and checked this certificate (i.e. TOFU), in which case it can proceed with rendering. Though it should probably still check CT and Convergence in the background.

      It may seem like I'm suggesting just piling on layers, but each one of them addresses specific problems and each has specific tradeoffs.
