A General Evaluation Pattern for Pseudo Random Number Generators

Many models have been designed for generating pseudo random numbers and there is the potentiality to design more. Among the mentioned generators, a few of them are applied in cryptography. Thus, there is an inevitable need among researchers and users for evaluating the generators. A variety of criteria are used for evaluation which have more or less or neutral importance depending on the way the generators are applied. Accordingly, some reliable sources pay attention to the particular criterion while overlooking others. In the present study, in addition to enumerating all of the popular criteria, there has been an attempt to classify them in the form of a general model. At the end, some suggestions are presented for the foremost priority in using and applying the criteria. With implementing this pattern all the criterions have been considered and on the other hand the probability of second type error will be reduced. Also, observance of the sequence of criterions would cause saving in time and costs.
