Abstract :
SMS4 algorithm is one of the block ciphers used in WLAN, and it is the first commercial block cipher opened by China. In this paper, the principle of SMS4 is introduced. And a one-time cipher algorithm based on SMS4 is proposed and realized, thus the security of the algorithm is improved. The symmetric keys are also one-time by Combining from symmetric key seeds in this paper. A Two-way Authentication is realized at last.
