ABSTRACT:
A method for recovering from encryption key variable loss, either inadvertent or the result of tampering. A predetermined key encryption key is encrypted with itself at the time when keys are first loaded, and the resultant key loss key is stored in non-volatile memory. This key loss key acts as a key encryption key for decryption of new shadow and traffic keys.
