Constructing a Hash Function Based on Logistic Mapping
构造基于Logistic映射的Hash函数

The one-way function of hash is an important tool of realizing effective and safe and credible numerical signature and authentication, it is an important part of safe authentication protocol. According to some shortcomings of a chaos-based hash algorithm presented in document, this paper puts forward a kind of solution project and algorithm, and does the emulational experiment to the algorithm, and also conducts a statistical analysis of the improved algorithm in confusion and diffusion properties, and therefore verifies the efficiency of the algorithm.
