Abstract
A communication system transmits and receives encrypted digital signal samples. The system includes a generator for generating digital signal samples to be encrypted and an encryption memory for storing the encrypted digital signal samples. The digital signal samples address the encryption memory which provides the encrypted digital signal samples responsive to the digital signal samples. The system further includes a transmitter for transmitting the encrypted digital signal samples and a receiver for receiving the encrypted digital signal samples. The system further includes a decryption memory for storing the digital signal samples at storage locations complimentary to the encrypted digital signal sample storage locations of the encryption memory. The encrypted digital signal samples address the decryption memory to cause the decryption memory to provide the digital signal samples responsive to the encrypted digital signal samples for reproducing the original digital signal samples.
