Abstract: Aiming at the problem that the existing one-dimensional chaotic system has small chaotic interval, Lyapunov exponent is small and the generated chaotic sequence is unevenly distributed, and the correlation is high, a new image encryption algorithm is proposed by this paper. The logistic chaotic mapping and tent chaotic mapping are cascaded by iteration based on Arnold transform, logistic and tent mapping. Experiments show that the algorithm effectively extends the key space of chaotic systems, has good encryption effect and security, and can resist several common attacks.
