A stream cipher based on a spatiotemporal chaotic system
TLDR
Numerical investigation shows that the cryptographic properties of the generated keystream are satisfactory, and the cipher seems to have higher security, higher efficiency and lower computation expense than the stream cipher based on a spatiotemporal chaotic system proposed recently.Abstract:
A stream cipher based on a spatiotemporal chaotic system is proposed. A one-way coupled map lattice consisting of logistic maps is served as the spatiotemporal chaotic system. Multiple keystreams are generated from the coupled map lattice by using simple algebraic computations, and then are used to encrypt plaintext via bitwise XOR. These make the cipher rather simple and efficient. Numerical investigation shows that the cryptographic properties of the generated keystream are satisfactory. The cipher seems to have higher security, higher efficiency and lower computation expense than the stream cipher based on a spatiotemporal chaotic system proposed recently.read more

A symmetric image encryption scheme based on 3D chaotic cat maps
TL;DR: The two-dimensional chaotic cat map is generalized to 3D for designing a real-time secure symmetric encryption scheme that uses the 3D cat map to shuffle the positions of image pixels and uses another chaotic map to confuse the relationship between the cipher-image and the plain-image, thereby significantly increasing the resistance to statistical and differential attacks.
