Pseudorandom Number Generator Based on Three Kinds of Four-Wing Memristive Hyperchaotic System and Its Application in Image Encryption

Table 1

Flow chart of the specific process of the PRNG design.

Initialization:
	While (key condition) do choose the last 22 binary decimal values from the sequences of 4D, 5D, and 6D continuous memristive hyperchaotic that called Xi_OUT, Yi_OUT, and Zi_OUT,
		Obtain bit stream based on XOR of until n = N end while
