Abstract
A method for detecting unauthorized use of a communication unit (102) in a secure wireless communication system includes monitoring (201) a wireless communication channel (103) presently supporting a secure communication. It is determined (202) whether the secure communication is encrypted with active system encryption parameters. When the secure communication is not encrypted with the active system encryption parameters, a communication unit (102) involved in the secure communication is indicated (203) as a potential unauthorized communication unit (102). The steps of monitoring, determining, and indicating are performed by a communication unit (102) or a central controller (101).
