Cryptanalysis of RC4-like stream ciphers

Stream ciphers, ciphers which encrypt data one bit or a few bits at a time, have been used for many years in environments where low delay and high speed are a requirement.;RC4, a stream cipher designed by Rivest for RSA Data Security Inc., has found several commercial applications, but little public analysis has been done to date. In this thesis, alleged RC4 (hereafter called RC4...
