Multiplicative congruential generators have been first suggested by D.H.Lehmer as an arithmetic procedure to generate pseudo random numbers. A mild variation of it is the linear congruence generator. Over many years both these generators were widely used in simulations and reported to have good statistical properties and favorable cycle length. Cryptanalysts have come up with numerous complex methods to cryptanalyze the generators mentioned above. We discuss a simple method to cryptanalyze both multiplicative and linear congruence generators, which make them unsuitable as raw input to simulations and various cryptosystem.
