这套NIST（国家标准与技术研究所）测试程序是一个统计包，包括16种测试手段。这些测试手段可测试由用作保密随机或者伪随机数发生器的硬件和软件产生的任意长的2进制序列的随机性。这些测试手段主要致力于判定可能存在于序列中的多种多样的非随机性。其中一些测试又可以分解成多种子测验。这16种测-Set NIST (National Institute of Standards and Technology) test procedure is a statistical package, including 16 kinds of testing methods. These testing methods to test the randomness of arbitrary length binary sequence generated by the hardware and software used as a the confidentiality random or pseudo-random number generator. These testing methods focused on the judgment may be present in a variety of non-random sequence. Some of these tests can be decomposed into a the seedy test. 16 measured
