… mail sent through Google is signed. Google can’t repudiate these signatures, but you have to trust them not to write new history. Matthew Green calls for the opposite: for Google to publish its old private keys to destroy this information.
Interesting take on the dangers of strong validation. I note that time-stamping the signatures would prevent Google both from writing new history, and from doing what Mr Green wants.
I haven’t taken the time to consider whether Mr Green’s point is valid, but i instinctively hope it isn’t because of what it would mean for the value of aiding truth-seeking.
