System and method for controlling access to a user secret using a key recovery field

A system and method for data recovery is described. In one embodiment, an encrypting system encrypts a message or file using a secret key (KS) and attaches a key recovery field (KRF), including an access rule index (ARI) and KS, to the encrypted message or file. To access the encrypted message or fi...

Zusammenfassung:	A system and method for data recovery is described. In one embodiment, an encrypting system encrypts a message or file using a secret key (KS) and attaches a key recovery field (KRF), including an access rule index (ARI) and KS, to the encrypted message or file. To access the encrypted message or file, a decrypting system must satisfactorily respond to a challenge issued by a key recovery center. The challenge is based on one or more access rules that are identified by the ARI included within the KRF.
