摘　　要：Satellite images are widely used for remote sensing and defence applications,however,they are subject to a variety of threats.To ensure the security and privacy of these images,theymust be watermarked and encrypted before communication.Therefore,this paper proposes a novel watermarked satellite image encryption scheme based on chaos,Deoxyribonucleic Acid(DNA)sequence,and hash algorithm.The watermark image,DNA sequence,and plaintext image are passed through the Secure Hash Algorithm(SHA-512)to compute the initial condition(keys)for the Tangent-Delay Ellipse Reflecting Cavity Map(TD-ERCS),Henon,and Duffing chaotic maps,respectively.Through bitwise XOR and substitution,the TD-ERCS map encrypts the watermark image.The ciphered watermark image is embedded in the plaintext image.The embedded plaintext image is permuted row-wise and column-wise using the Henon chaotic map.The permuted image is then bitwise XORed with the values obtained from the Duffing map.For additional security,the XORed image is substituted through a dynamic S-Box.To evaluate the efficiency and performance of the proposed algorithm,several tests are performed which prove its resistance to various types of attacks such as brute-force and statistical attacks.
