Based on plaintext information, a dynamic chaotic color image encryption algorithm is proposed as a solution for the security problem in image data transmission, Comparatively, the existing one has the characteristics of high key acquisition complexity and low encryption speed. Firstly, normalize the RGB components of the images so as to obtain the dynamic key associated with the plaintext, which encrypts images with any shape by rearranging and combining pixels from the original image. Secondly, the parameter offset key is introduced as the initial parameter of the logistic map to generate a high-precision chaotic encryption sequence. The chaotic value sequence is stored for disordered pixels according to the image size, and enlarged and rounded to enhance the pixel value diffusion of the original image. Finally, RGB components are fully fused and uniformly distributed to form a completely encrypted image. According to the experimental results and security analysis, the proposed algorithm is effective against differential attacks, with low complexity, high efficiency, and faster encryption speed.
With the development of Internet of Things technology and the people’s pursuit of high-quality life, the development of smart homes is becoming more and more diversified, paying more attention to reducing costs, increasing benefits and user experience. For the scene where lights and images change synchronously in smart homes, the current technology used in related products is a solution for external hardware processing equipment, which has problems such as high hardware cost, complex configuration, only supporting external HDMI sources, etc.. Combined with the above situation, this paper proposes a smart home lighting linkage system that is suitable for market demand, easy to promote, apply and implement. Through ZigBee, Bluetooth networking technology, color segmentation technology, signal processing technology, etc., this solution designs and implements an adaptive lighting linkage smart home system based on the color change of the TV screen. The scheme has been proved to have the characteristics of low cost, good experience and stable effect in practical application, and achieved the expected research goals.
