Abstract

This invention solves the problem of achieving syn- chronization while using encryption devices whose syn- chronization requirements are inherently unknown. Unless sync is achieved, data will not be decryptable. In the Advanced Securent (ASN) System, such synchroniz- ation failures can lead to corrupted data being stored in a database and a high error rate in an over-the-air-rekeying (OTAR) message to a subscriber unit.
