Abstract: The current article statistically analyzes several PRNG for well-known high-speed stream ciphers. The study focuses on frequency detection, uniformity distribution alongside with randomization in the generated sequence. The purpose of this work is to show if there is a signature left by these PRNG in theirs produced sequence. In addition, the work compares these PRNG to indicate which is the safest against statistical cryptanalysis.
