Abstract
Symmetric-key encryption method for transforming a sequence of plaintext symbols into a sequence of ciphertext symbols, includes an iterative encryption process including: computing an altered current internal state by combining a current internal state with a current memory symbol; computing a next internal state from the altered current internal state; generating a keystream symbol from the next internal state; verifying whether the generated keystream symbol satisfies a condition related to data-format/syntax rules; iteratively computing next internal states and iteratively generating keystream symbols; and iteratively encrypting plaintext symbols by employing next keystream symbols to obtain the sequence of ciphertext symbols.
