At Crypto 92, the author put forward a new approach to key-escrow, whereby (1) trustees have guaranteed pieces of a secret key, (2) too few trustees cannot easily reconstruct the key, but (3) sufficiently many trustees can easily reconstruct the entire key. An additional example of key-escrow scheme with similar properties is provided by the Clipper Chip [2].
