摘要

As the core of cryptography, hash function is one of the basic techniques for information security. During the last few years, considerable effort has been devoted to research on chaos-based hash functions. Nevertheless, the corresponding analysis of them lag far behind. In this paper, a new efficient scheme for parallel hash function based on high-dimensional chaotic map is proposed. In the proposed scheme, the confusion as well as the diffusion effect is enhanced significantly by utilizing two nonlinear coupling parameters. Theoretical and experimental results indicate that the proposed scheme can satisfy all performance requirements of hash function such as desired statistical properties and strong collision resistance. At the same time, the proposed scheme can keep the parallel merit and message sensitivity with high potential to be adopted for network security.
