A Novel Multiband Remote-Sensing Image Encryption Algorithm Based on Dual-Channel Key Transmission Model

Abstract

With the rapid development of remote sensing technology, satellite remote sensing images have been involved in many areas of people’s lives. Remote sensing images contain military secrets, land profiles, and other sensitive data, so it is urgent to encrypt remote sensing images. This paper proposes a dual-channel key transmission model. The plaintext related key is embedded into the ciphertext image through bit-level key hiding transmission strategy, which enhanced the ability of ciphertext image to resist known-plaintext attack and chosen plaintext attack. In addition, a multiband remote sensing image encryption algorithm based on Boolean cross-scrambling and semi-tensor product diffusion is designed. Firstly, the pixel positions of each band of the remote sensing image are disturbed. Then, the random sequence generated by the four-dimensional chaotic system is processed and deformed to obtain a Boolean matrix. Based on the generated Boolean matrix and certain rules, the cross-confusion between the bands is carried out. Finally, the semi-tensor product operation is used in the diffusion process. Simulation results and experimental analysis show that the proposed algorithm obtains a larger key space and has stronger antiattack ability than other remote sensing image encryption algorithms. It can meet the security transmission of multiband remote sensing image in open space.

A robust multi-chaotic remote sensing image encryption scheme based on RNA and immune algorithms

“…The information entropy for numerous encrypted images was computed in this paper, and the results, as outlined in table 5, demonstrate that the entropies of all encrypted images closely approximate 8. Therefore, it can be concluded that our scheme has an average entropy of 7.9997 and is superior to the schemes in [28][29][30][31][32].…”

Remote sensing image encryption algorithm based on novel hyperchaos and an elliptic curve cryptosystem

“…[1] Since the 1920s, remote sensing has been employed in diverse military applications, including target detection, positioning and intelligence gathering. [2] With the advent of new data acquisition platforms, spectrum sensors can now be deployed on smaller platforms such as robots and unmanned aerial vehicles (UAVs). The remarkable mobility and cost-effectiveness of these new platforms make them an optimal choice.…”

“…Generally speaking, the image encryption algorithm includes scrambling and diffusion. In order to obtain better an encryption effect, most of the existing image encryption schemes are organically combined with DNA coding [ 5 ], S-box transformation [ 6 ], compressed sensing, bit level [ 7 ], semi-tensor product operation [ 8 , 9 ], fractal model [ 10 ], and other advanced technologies.
