改进型NIST测试对ZUC算法随机序列的可视化检测
Using improved NIST for visual detection of random sequences of ZUC algorithm
摘要
Abstract
The information is encrypted by using the random cipher algorithm to ensure the security of information.Testing a encryption algorithm generally used NIST test standard.For traditional detection methods,there are not a high utilization rate of key stream,the result is not intuitive and so on.This paper proposed a new method to improve the traditional detection method.Firstly,it calculated the key stream by segmenting them to increase the utilization of key stream,which made the result more accurate.It grouped data and transformed the results into 2D visualization images by the formula.It made the result more intuitive.It's better to show the characteristics of the ZUC algorithm using the proposed method to detect ZUC algorithm.It was found that the sequence ciphers generated by ZUC algorithm has good randomness.When the key stream is longer,the degree of characteristic points' aggregation is higher on the image.关键词
