Abstract
The rapid development of science and technology has brought convenience for photographing and sharing images. However, with the rapid increase of image data, security problems such as leakage and tampering also occur frequently. The application of image encryption technology is imminent, especially the encryption of color images is in urgent need of improvement and development. The traditional encryption technology is mainly aimed at data stream encryption, which has low efficiency, large amount of calculation and certain limitations. Based on transform domain encryption, the image is transformed from spatial domain to frequency domain for encryption, and then transformed to spatial domain, which belongs to a kind of lossy encryption. Encryption based on chaos has large key space, simple implementation and fast encryption speed. Generally, multiple chaotic systems need to be used to enhance the security of encryption. Therefore, a simple and secure spatial encryption algorithm for RGB three channels of color image is designed in this paper. Firstly, a safer chaotic sequence is generated by logistic sine cosine mapping, and then four rounds of scrambling and diffusion pixels are designed by chaotic sequence. Finally, In a series of security analysis experiments, the security and effectiveness of color image encryption algorithm based on logistic sine cosine mapping are verified.
