Re: [dns-privacy] What about CGA-TSIG as a solution for DNS privacy?

2014-10-28 Thread Christian Huitema
CGA-TSIG is a possible solution to the secure-provisioning problem. The IPv6 CGA address contains a hash of a public key used to secure the service. If the address is provisioned in a secure manner, then the client can authenticate the resolver, by verifying that the resolver's certificate
