Hardware implementation of a strong pseudorandom number generator based block‐cipher system for color image encryption and decryption

Summary This paper proposed a hardware architecture of a strong block‐cipher system dedicated to digital image encryption and decryption. On the one hand, a pseudorandom number generator (PRNG) based on two 3D chaotic systems is created to produce strong keys. On the other hand, a robust algorithm i...
