Finally, an image encryption algorithm based on PRNG is adopted. In addition, PRNG has passed the NIST 800.22 and ENT test, which shows that PRNG has good statistical characteristics. ![]() In order to prove its potential application in secure communication, the security of PRNG based on this scheme is analyzed from the perspective of cryptography. The principle of this method is to obtain pseudorandom numbers with good randomness by coupling XOR operation on the three kinds of FWMHSs with different dimensions. ![]() In this paper, we propose a method to design the pseudorandom number generator (PRNG) using three kinds of four-wing memristive hyperchaotic systems (FWMHSs) with different dimensions as multientropy sources.
