There are two phases to test the random number generator process. First you need a source of entropy  that is impossible to guess like the weather. Second you need a deterministic algorithm to...Do random number generators really exist?
There do exist some advanced random number generators that use computers to produce random sequences. However, they take their starting point from a true random source – such as the sound wave of a geothermal movement.What is the logic behind random number generator?
Random number generation is a process by which, often by means of a random number generator, a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance is generated. This means that the particular outcome sequence will contain some patterns detectable in hindsight but unpredictable to foresight. True random number generators can be hardware random-number generators that generate random numbers, wherein each generation is a function of the current value of a
