Does anyone know of a trapdoor one-way function whose trapdoor can be locked after use?
It can be done with secure hardware and/or distributed trust, just delete the trapdoor key, and prove (somehow?) you've deleted it. It looks hard to do in "trust-the-math-only" mode... -- Peter Fairbrother --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
