So I looked up the standard. +I was surprised to note that they have already considered these issues, in +section 15.1.2, <http://openid.net/specs/openid-authentication-2_0.html#anchor41>. + +It says: + +"Using SSL with certificates signed by a trusted authority prevents these kinds of +attacks by verifying the results of the DNS look-up against the certificate. Once +the validity of the certificate has been established, tampering is not possible. +Impersonating an SSL server requires forging or stealing a certificate, which is +significantly harder than the network based attacks." + +With regards to implementation, I am surprised that the libraries don't seem to +do this checking, already, and by default. Unfortunately, I am not sure how to test +this adequately, see <http://bugs.debian.org/466055>. -- Brian May |
