I’ll be presenting this to the CFRG (Crypto Forum Research Group) at IETF 111, late on Friday evening (London time)
“A ‘Duck Test’ for End-to-End Secure Messaging”
https://alecmuffett.com/alecm/ietf-111/draft-muffett-e2esm-v1.18a.pdf
It’s a simple, robust, and easily understood metric for people to use when judging assertions like:
“The GCHQ ‘Ghost’ Proposal does not harm End-to-End Security”
…claims which are popular in (typically) governmental or cybersurveillance literature, but which are challenging to rebut for want of a standard metric.
I will be updating this posting with a companion video, sometime in the next few days.
