A New Design for High Throughput Linear PRNG
As we know that pseudo random number generator is used to generate a long period random number sequence but the output random numbers of such generators are predictable due to their linear structure. When we want to design the fast circuit or fast system naturally we have to go for some solutions. To overcome this problem here presenting a new method for reseeding-mixing to extend the system period length and to enhance the statistical properties of a chaosbased pseudo random number generator (PRNG).In this model the reseeding method is used to remove the short periods of the digitized logistic map and the mixing method is for extends the system period length to 2253 by “XORing” with a DX generator. By that we will achieve a High throughput rate that is more than 6.4 Gb/s by producing the multiple bits per iteration and the hardware-efficiency is also validated. In this the output sequence of the RM-PRNG is used as a key to encryption and Decryption models. The simulation results are obtained by using modelsim.
