A fast adaptive stream cipher algorithm and expanded search

To solve the problem of traditional stream ciphers can not transmit through the public channel and the construction of high-strength cipher key generator, the paper presents the minimum power clock function driven by a parallel clock-control sequence and chaotic cascade function made of multiple Logistic function, which are used to built the self-reference model and chaotic module; it designs an adapt controller independent of the key generator and encrypt module, achieve controlling encryption and transmission process by multi-threaded code; it makes a high-strength key generator with sure differential transformation and pseudo-random horizontal level disturbance wheel key method of AES and S-box of Camellia, which makes the sub-key and the key generator´s internal station become vogue and uncertain within controlled area that does not depend on the secret channel, the model achieves an exponential growth in the key space and the same application scope of traditional stream cipher model. The new protocol model features can be seen under the actual operation of modifying RC4 and real-time RC5 algorithm.
