ABSTRACT:
A key variable correction scheme allows errored encryption key material in mobile and portables radios to be quickly identified and corrected. The errored encryption material can be corrected automatically by a key management controller, once detected. Consequently, a mismatch problem can be diagnosed and resolved in a manner which is automatic, therefore quick and efficient, and in a way which overcomes the difficulty which users have in identifying by themselves a mismatch condition since the result is often only silence out of their respective radio speaker. Once the mismatch is corrected by the reassignment of correct keys, the user is free to join the radio call already in progress.
