Rosario Gennaro, Donald Byron Johnson, Paul Ashley Karger, Stephen Michael Matyas Jr, Mohammad Peyravian, David Robert Safford, Marcel Mordechay Yung, Nevenko Zunic: Two-phase cryptographic key recovery system. International Business Machines Corporation, William A Kinnaman Jr, August 10, 1999: US05937066 (238 worldwide citation)

A cryptographic key recovery system that operates in two phases. In the first phase, the sender establishes a secret value with the receiver. For each key recovery agent, the sender generates a key-generating value as a one-way function of the secret value and encrypts the key-generating value with ...
