Abstract (en)
[origin: CA2371446A1] Plaintext elements and masking array elements are converted into digits in another base (step 2). The resulting digits are combined modulo the new numb er base and the result is converted back into elements using the original numbe r base resulting in ciphertext elements (step 4). For recovery of the plaintex t, the cyphertext elements and masking array elements are converted again into digits in the same number base as used for encryption and a reverse arithmet ic 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.
