DSP Chaotic image encryption based on Chen system
LI Jing-yuan · Electronic Design Engineering · 2013
A novel method for realizing chaotic digital image encryption and its hardware implementation based on DSP is presented.By the discrete and digital process technology,the three-dimensional Chen chaotic system is made discrete and Chen chaotic iteration sequence is generated by using Hardware Description Language C and DSP technology.Red,green,and blue tricolor signals of the image are encrypted and decrypted,respectively.On the basis of the DSP exploitation platform with TMS320VC55O9A chip.a gray image with an BMP format is taken as an example.The digital image encryption and decryption algorithm using Chen chaotic sequence is designed,and DSP hardware implementation result is given.
