In this paper the authors analyze Pseudo-Random Number Generators (PRNG) which uses permutation(s) as their internal state. The predecessor of this approach is the RC4 algorithm by the researcher, found many software applications, however a significant number of attacks were found against it, many of them distinguishing the produced output from random. In this paper they also try to find out how complex an RC4-like PRNG would need to be to actually produce pseudorandom output.
