“…The traditional text encryption algorithms such as DES and AES are not suitable for image encryption. In recent years, image encryption based on chaotic systems [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ], cellular automata [ 8 , 9 , 10 , 11 , 12 ], DNA encoding [ 13 , 14 , 15 ], bit plane decomposition [ 16 , 17 , 18 , 19 , 20 , 21 ], and elliptic curve [ 22 , 23 , 24 , 25 , 26 ] is the mainstream of cryptography. Due to the significant properties of unpredictability, ergodicity and initial state sensitivity, the chaotic system becomes a good choice for encryption [ 27 ].…”
