Encryption is once again a hot topic, and there’s much to discuss at IETF 99 this week in Prague. This time the hottest action will definitely be in the Transport Layer Security (TLS) working group. TLS is considering everything from privacy implications for TLS1.3 to how to reduce handshake latency. As mentioned in previous Rough Guide blogs on the topic, the working group is busy on the completion of the TLS 1.3 specification. It has completed working group last call, and the working group is addressing the comments received during that process. Draft 21 was released on 3 July in anticipation of this week’s discussion.
