Abstract:
A system for encrypting a first key, comprising:a private information encoder having an encoder input operatively coupled to receive private information, the private information encoder for encoding the private information received at the encoder input to produce encoded private information at an encoder output; a first encryptor having a first input coupled to the private information encoder output to receive the encoded private information and a second input operatively coupled to receive the first key, the first encryptor for encrypting the first key responsive to the encoded private information to produce a once encrypted first key at a first encryptor output; and a second encryptor having a first input coupled to the first encryptor output for receiving the once encrypted first key and a second input operatively coupled to receive a second key, the second encryptor for encrypting the once encrypted first key responsive to the second key to produce a key recovery file comprising a twice encrypted first key, and for providing the key recovery file at a second encryptor output coupled to a system output; wherein the private information is generally known only to a first party; further wherein the twice encrypted first key can only be decrypted by a second party to yield the once encrypted first key; and further wherein the party and the second party are different parties.
