This paper is intended to provide the readers with a clear understanding of the modification done to the pseudo-random number generator (PRNG) arc4random. The arc4random PRNG was modified to implement a non-deterministic rekey interval. A comparison was made with the unpatched version regarding performance and the rekey interval's randomization. All measurements were done when the rekey was performed. A slight increase in performance was observed, and the rekey interval was randomized as expected.
