In this paper, a novel image encryption algorithm based on the fractional-order chaotic system and compression sensing algorithm is proposed. Firstly, the dynamical characteristics of the fractional-order chaotic system are analyzed. The hardware circuit is designed in and realized on the DSP. Secon...
