Abstract

In this paper, a new word-oriented Stream Cipher algorithm with a key length of 256 bit is designed and analyzed. The proposed algorithm is highly resistant against the 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 1214 2. With the improvement of certain nonlinear kernel of some algorithms, such as SNOW2 and using it as a nonlinear part of encryption, the proposed algorithm is much more resistant than other similar ciphers against distinguishing and Algebraic Attacks. According to the security analysis, the complexity of Distinguishing Attack is 9033 O(2 ) and complexity of Algebraic Attacks is 2839 O(2 ).
