Chaos-Based Application of a Novel Multistable 5D Memristive Hyperchaotic System with Coexisting Multiple Attractors

Algorithm 1

RNG design algorithm pseudocode.

(1)	start
(2)	Given the initial condition, parameter value, step value Δh and sampling interval of chaotic system (4);
(3)	while (least 100 M. Bit data) do
(4)	Using RK4 algorithm to solve chaotic system (4), 32 bit x, y, z, , u has obtained;
(5)	Select the last 22 bit number of 32 bit x, y, z, and ;
(6)	Obtain the bit stream of the chaotic system (4) by XOR x and y, z, and ;
(7)	Get test bit stream according to 5 and 6;
(8)	end while
(9)	End
