Abstract EN
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.
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 order to prove its potential application in secure communication, the security of PRNG based on this scheme is analyzed from the perspective of cryptography.
In addition, PRNG has passed the NIST 800.22 and ENT test, which shows that PRNG has good statistical characteristics.
Finally, an image encryption algorithm based on PRNG is adopted.
In the encryption algorithm, the optimized Arnold matrix scrambling method and the diffusion processing based on XOR are used to obtain the final encrypted image.
Through the evaluation of encryption performance, it is concluded that there is no direct relationship between the pristine image and encrypted image.
The results show that the proposed image encryption scheme has good statistical output characteristics and security performance in line with cryptography.
