In this Letter, a new image encryption scheme is presented, in which shuffling the positions and changing the grey values of image pixels are combined to confuse the relationship between the cipher-image and the plain-image. Firstly, the Arnold cat map is used to shuffle the positions of the...

We present a numeric chaos-based cryptosystem, implemented on a Digital Signal Processor (DSP), which resists all the attacks we have thought of. The encryption scheme is a synchronous stream cipher. Its security arises from the properties of the trajectories in a chaotic attractor, reinforced by...
An image encryption scheme based on compressive sensing (CS) and chaos is proposed. Firstly, the plain image is transformed into the sparse coefficient matrix by discrete wavelet transform (DWT). Secondly, to achieve compression and encryption, the sparse coefficient matrix is measured by the measur...
Firstly a chaos sequence is generated, then the pre-encrypted image based on XOR operation and cycle shift is obtained, and encrypted image is achieved by Arnold mapping on the pre-encrypted image, The experimental results show that this method has the advantages of good encryption effect, fast...
