This paper introduces an image encryption algorithm based on 2D-Sine-Cosine chaotic mapping and compressed sensing technology. This algorithm introduces a novel 2D-Sine-Cosine chaotic mapping function. By using nested sine and cosine functions and selecting appropriate parameters, chaotic oscillators with strong randomness, wide traversal range, and complex nonlinear behavior trajectories can be generated in phase space. Combined with compressive sensing theory, image compression and encryption can be achieved. The experimental results show that the encryption algorithm proposed in this paper has good performance.
