Scouting report

Found the protocol flaw in the NSA’s Clipper chip escrow scheme in 1994 and published it, which did more to end mandated key escrow than any amount of lobbying. Later led state-commissioned source reviews of US voting systems, published work on the vulnerabilities of master-keyed physical locks and wiretap systems, and became a law-school professor arguing the same points to a different audience.

Curator’s note

Has broken the government’s preferred backdoor design once already.
