Encryption and return method of inspection image of UAV converter station based on chaotic sequence

Abstract

Conventional encryption and return method of UAV converter station inspection image mainly uses Fibonacci scrambling technology to generate two-dimensional encryption mapping, which is easily affected by pixel iteration, resulting in a high difference in peak signal-to-noise ratio. Therefore, a new encryption and return method of UAV converter station inspection image is needed, and an encryption and return algorithm of UAV converter station inspection image is designed based on chaotic sequence. The experimental results show that the difference between the peak signal-to-noise ratio (PSNR) before and after the encrypted return of the inspection encrypted image of the UAV converter station is small, which proves that the encrypted return of the inspection encrypted image is effective, reliable and has certain application value, and has made certain contributions to improving the inspection effect of the UAV converter station.
