Verifiable Partial Key Escrow

Mihir Bellare and Shafi Goldwasser

Abstract: One of the main objections to existing proposals for key escrow is that the individual's privacy relies on too high a level of trust in the law enforcement agencies. In particular, even if the government is trustworthy today, it may be replaced by an un-trustworthy government tomorrow which could immediately and suddenly recover the secret keys of all users.
