Abstract

This invention is a password protection key to allow a Key Management Controller (KMC) to unlock a radio for a user in the event that the user has forgotten the password. This invention provides the following features: 1. A user can gain access to a radio aRer the password has been forgotten or corrupted. 2. The secrecy of the password is maintained, only the protection key is known by the KMC. This requires a cryptanalyst to possess both the protection key known only to the KMC as well as the radio itself; in order to gain access to the radio's shadow keys. 3. An audit trail is created so that a password change record can be tested in a security audit. This allows bona fide users to know that the password has been changed in the event that a cryptanalyst has breached the security ofthe password.
