ABSTRACT:
A system for communicating simultaneous encrypted messages in a jamming eronment with a low opportunity for depth exploitation. The system includes a plurality of transmitters, each having a high speed key generator for producing a plurality of pseudorandom bit streams. The bit streams are combined with a unique identifier in each transmitter to produce a single unique key stream, which may be added to a binary data stream to create an encrypted message for transmission. The receiver includes a single key generator identical to those in the transmitters and a plurality of combiners and correlators to enable simultaneous recovery of each transmitted encrypted message.
