ABSTRACT:
The device is an IFF Authentication System for sending and receiving of coded intelligence. So as to reduce an alien's chances of using the intelligence transmitted, the system uses a clock to provide signals for additional encipherment or scrambling of the coded intelligence. The clock is easily synchronized and provides continuously changing code encipherment for maximum protection and is connected into the system at a variety of predetermined places depending on the componential design of the particular system being used.
