Application of Wavelet Transform in Information Security for Sequence Randomness Test

对当前信息安全系统中常用的随机序列检测方法进行研究和分析,利用小波分析理论提出一种新的随机检测方法,该方法可以用于对随机数产生器的评价、有助于评估密码算法的安全性、有助于检查随机数产生器和密码算法的实现上的错误。

This paper studies and analyses the common test methods of sequence randomness information security systems and then presents a new test method of sequence randomness using wavelet transform. This method can be used for the evaluation for the random number generator and is helpful in estimating the security of cryptographic algorithms and checking out errors in implementation of random number generator and cryptographic algorithms.
