A cryptographic device and method provide a repertoire of mappings and associated inverse mappings between plaintext and cipher-text vectors. The plaintext (200) is partitioned block-by-block, the block size being userselectable such as N characters. Each mappings maps between a pair of N-dimensional plaintext (200) and ciphertext vectors (280). The mapping or associated inverse mappings is implemented by a matrix with N × N matrix elements, where each element is allowed to take on a range of L values. By permuting the matrix elements within their range, the repertoire has a size = L exp (N × N). A secret key shaved between the users includes information about the selected mapping or associated inverse mapping and may include values N and L. In the preferred embodiment, a pseudo-random vector (247) that varies block-by-block is added as another component to the ciphertext vector (280).
