Hi, Wouter, Your proposal provides a useful scheme to publish and fetch the public key of the server. It's the most important point of my solution, I mean, only when the client gets the public key of the server, it can then encrypt the request information and its own public key in the request me

[dns-privacy] Fwd: Encrypt the signalings between stub and recursive resolvers under UDP

2015-03-11 Thread Phillip Hallam-Baker
The proposal is a reasonable approach and not overly complex. The question that concerns me though is how the client authenticates the resolver. Without authentication, encryption is useless because you could be having the conversation with Mallet. Using DNSSEC for that is problematic since the cr

Hi, Phillip, You are right. In order to make this solution work securely and efficiently. Except the issues you mentioned, the key rollover schemes for both client and recursive server should be designed. BR, Zhiwei 在 2015-03-11 20:26:13,"Phillip Hallam-Baker" 写道: >The proposal is a reasonab
