key recovery

While sometimes simply the process by which a key is retrieved from key escrow (which see in the hard copy dictionary) key recovery also refers to a substitute for the failed Clipper chip/Capstone initiative (which see in the hard copy dictionary). In this scheme a copy of the key, in a separately encrypted key recovery field, is always sent along with the data which it encrypts. A predetermined private sector 'Key Recover Center' can decrypt the key recovery field when requested by an authorized party (e.g. a government agency with a court order). A new cryptography export policy which took effect in late 1996 allows companies in the United States to export cryptographic algorithms using up to 56 bit keys if they agree to add a method for key recovery within their product within the next two years. Also see recovery key and TACDFIPSFKMI.
