Abstract

Aiming at the problem of improving the security of inspection image in the case of limited computing resources in substation intelligent patrol, this paper proposes a secure encryption algorithm for substation inspection image based on chaotic mapping and DNA coding. The algorithm uses the hash value of the image as the original key, realizes the secure sharing of the original key, and expands the key space. The algorithm uses one-dimensional chaotic map to generate chaotic sequence, and uses chaotic sequence to block encryption of image. Then, on the basis of DNA coding, the algorithm performed DNA scrambling encryption and DNA diffusion encryption on the image in turn. Experimental results show that this algorithm can effectively resist exhaustive attack, brute force attack and statistical analysis attack, and can effectively improve the security of inspection image. It has a broad application prospect in the field of substation intelligent patrol.
