ABSTRACT:
An encryption and decryption system performs encryption and decryption using the residue number system. A binary input signal is converted into residue number system representation in a binary to residue converter. Pseudo random numbers, generated from pseudo random number generators, are then added to the converted input signal in modular, that is, residue number system, adders. The outputs of the modular adders are converted into binary or mixed radix digit representation and are then transmitted to the location of a decrypter. The transmitted binary or mixed radix digit signal is converted back into residue number system representation in another converter and is then decrypted by subtracting the pseudo random number sequence. This decrypted signal is then converted into binary representation. The binary representation of the decrypted signal resembles the input signal.
