Construction of Hash Function Algorithm Based on Chen Chaotic System

In this paper, Chen chaotic system with relatively high complexity is used to construct hash function. Aiming at the low efficiency of hash function constructed by high-dimensional continuous chaotic mapping algorithm, an algorithm for grouping and mapping plaintext blocks is proposed. The experimental results show that compared with the existing mainstream chaotic hash algorithm, the avalanche characteristics and disordered distribution of this algorithm still remain, and the confusion and diffusion are more stable. At the same time, this algorithm is very suitable for running on parallel systems.
