A New Adaptive SSC and SSSC Stream Cipher Model Design and Implementation

Abstract:

To solve the problem of construction for stream cipher key generator and the problem of SSC/SSSC stream ciphers need to relay on the secret channel to transmit the key, it presents a new clock function drive by a 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 design a adapt controller independent of the key generator and encrypt module, achieve controlling encryption and transmission process by multi-threaded code;it makes a key generator with transformation ranks and wheel key method of AES and S-box of Camellia, which makes the sub-key and the key generator`s internal station become a insufficient condition that does not need to depend on the secret channel, the model achieves a exponential growth in the key space and the same application scope of traditional SSC and SSSC model. The new protocol model features can be seen under the actual operation of modifying RC4 algorithm.
