文摘
- •
A simultaneous image encryption–compression scheme based on 2D CS and hyperchaos is proposed.
- •
The nonlinear cycle shift operation controlled by a hyper-chaotic system is used for diffusion.
- •
The hyper-chaotic system with good randomness and sensitiveness is used to generate random sequences.
- •
The data of the ciphertext is decreased and the security is improved due to double encryptions.
