随机数序列在密码学中有着至关重要的作用,实际应用中考虑到序列生成的时间和复杂度,通常使用的是存在某些缺陷的伪随机数序列,它们给密码系统带来了一定的风险性。因此,需要使用随机性测试来对生成的序列进行检验,NIST在一个测试包中收录了16个随机性测试,这是目前较为常用的测试包之一,它们相互间的关系及其优劣性一直是一个值得探讨的问题。 The random number sequence plays an important role in cryptography. In practical applications, considering the time and complexity of sequence generation, pseudo-random number sequences with some defects are usually used, which bring a certain amount of Risk. Therefore, we need to use the random test to test the generated sequence. NIST includes 16 random tests in a test package, which is one of the more commonly used test packages. Their relationship with each other and their advantages and disadvantages It has always been a question worth exploring.
