ABSTRACT:
A communication system comprises a covert channel detector. The covert channel detector can be used in a multi-level security system (MLS) or multiple single levels of security (MSLS). The covert channel detector detects covert channels in a cryptographic system. The cryptographic system can be used in a military radio system.
