The Noise Protocol Framework April 2016
WhatsApp just announced their integration of the Signal protocol (formerly known as the Axolotl protocol). An interesting aspect of it is the use of a TLS-like protocol called Noise Pipes. A protocol based on the Noise protocol framework, a one-man work led by Trevor Perrin with only a few implementations and a moderately long specificiations available here. I thought it would be interesting to understand how protocols are made from this framework, and to condense it in a 25 minutes video. Here it is.
