Low power pseudo-random number generator based on lemniscate chaotic map

Lemniscate chaotic map (LCM) provides a wide range of control parameters, canceling the need for several rounds substitutions, and excellent performance in confusion process. Unfortunately, hardware model LCM is complex consumes high power. This paper presents proposed low power called practical lemniscate (P-LCM) depending on trigonometric identities to reduce complexity conventional model. The designed implement into field programmable gate array (FPGA) board, Spartan-6 SLX45FGG484-3. achieves 48.3 % reduction used resources 34.6 consumption compared LCM. We also introduce new pseudo-random number generator based P-LCM perform randomization tests encryption system.
