Abstract
Stream ciphers, including synchronous stream ciphers, self-synchronizing stream ciphers, and totally asynchronous stream ciphers, employ a working key and a quasigroup transformation, where the quasigroup used is based on an initial secret key. Error-correction and pseudo-random number generation improver methods also employ quasigroup transformations.
