Randomness detection method and device for safety protection product of industrial control system

The invention discloses a randomness detection method. The randomness detection method comprises the following steps: S1, completing calculation of the number F32 of matrixes with the rank of 32 and the number F31 of matrixes with the rank of 31 of sequence data to be detected; S2, calculating a statistical value V of the number F32 of the matrixes with the rank of 32 and the number F31 of the matrixes with the rank of 31 obtained in the step S1; and S3, based on the statistical value V obtained in the step S2, analyzing and judging whether the final detection result of the matrix rank is that the detection is passed or not. According to the method, the problems of complex execution process and low inspection efficiency when matrix rank detection is realized in a safety protection product of an industrial control system are solved. 本发明公开了一种随机性检测方法，所述随机性检测方法包括：S1：完成待检测序列数据的秩为32的矩阵个数F32和秩为31的矩阵个数F31的计算；S2：对步骤S1中的得到的秩为32的矩阵个数F32和秩为31的矩阵个数F31完成其统计值V计算；S3：基于步骤S2得到的统计值V，分析判断并得到矩阵秩的最终检测结果是检测通过或检测不通过。通过本发明方法解决了矩阵秩检测在
