In this paper, we designed and analysed a new word-oriented stream cipher algorithm with a key length of 256 bit. The proposed algorithm is highly resistant against known attacks. The main principles of the algorithm are based on improved word-oriented shift registers in clock control mode with cyclic period greater than . With the improvement of certain nonlinear kernel of some algorithms, such as SNOW2 and using it as a nonlinear part of encryption, resulted algorithm is much more resistant than similar samples against distinguish and algebraic attacks. According to security analysis, complexity of distinguish attack is and complexity of algebraic attacks is .
