Digital Image Encryption Algorithm Based on Hyperchaotic Sequence
D. Tian · Microelectronics & Computer · 2008
An improved image encryption method is proposed based on chaotic sequence and image encryption technology. Firstly, chaotic sequences are generated based on Hyperhenon and applied to pre-encrypt the image; then further processing are used for retreated the image, including renew magic-cube scrambling based on Kawakami mapping. The effect of encryption is also analyzed by using the method of accessing. Simulation results indicate that the method has good efficiency and security characteristic.
