Abstract: Chaotic stream cipher encryption algorithms based on logistic mapping and lorenz equation are proposed in this paper. The photo encryption result using C program is given. The speed of the algorithm based on logistic mapping is faster than the other, the latter is more secure. The research shows that it is safe and effective to generate stream ciphers using chaos.
