ABSTRACT:
Plaintext elements and masking array elements are converted into digits in another number base. The resulting digits are combined modulo the new number base and the result is converted back into elements using the original number base resulting in ciphertext elements. For recovery of the plaintext, the ciphertext elements and masking array elements are converted again into digits in the same number base as used for encryption and a reverse arithmetic combination of these digits is employed, modulo the new number base, and the result of the combination is converted back into elements in the original number base resulting in the original plaintext elements.
