摘要
随机序列在密码技术中占有非常重要的地位,随机性检测利用概率统计的方法对随机序列的随机性进行分析测试。美国国家标准与技术研究院(NIST)和我国国家密码管理局都发布了各自的随机性检测规范,二者都将单比特频数检测和块内频数检测作为其检测项。研究了单比特频数检测和块内频数检测的快速实现,提出了三种新的快速实现算法。这三种算法可以使单比特频数检测、块内频数检测和两种检测综合实现的速度分别提升29.2倍、15.5倍和32.8倍。
Random sequence plays a very important role in the crypto technology. Randomness test, by using the method of probability statistics, analyzes and tests randomness of the sequence. US National Institute of Standards and Technology and China National Cryptography Administration respectively released their randomness test specifications. These two specifications both take monobit frequency test and frequency test within a block as the test items. This paper discusses the fast implementation of monobit frequency test and frequency test within a block, analyzes the hotspots, and proposes three fast implementation algorithms. These new algorithms can greatly improve the speed of monobit frequency test, frequency test within a block and their combined implementation.
