Abstract:
This article implements the algorithm of using a random eventthe mouse movement tracks to produce real random numbers. Compared with the usual randomnumberproducing algorithm based on mouse, this one enjoys a higher randomicity in the process of sampling and getting original data. In addition, it does not need the extra circuit or facilities that other physical processes, the algorithms producing real random number. As a result, its costs will be reduced and the problem of a high expanse to produce real random numbers will be solved. The result of testing the uniformity and independence of the random numbers generated shows that the numbers produced by this algorithm have a fine statistical property. Moreover, the result of testing its program execution time proves that its time expending is very short.
Key words: random number; pseudorandom number; mouse moving path
