摘　　要：提出一种基于耦合动态整数帐篷映射的并行Hash函数。针对数据量较大、处理速度较慢等问题,采用MD6算法框架,利用多核处理器技术并行处理数据。同时在压缩函数中,利用双向耦合映像格子模型进行扩散,用动态整数帐篷映射代替传统的逻辑函数。实验结果表明,该算法可根据需要获得不同长度的Hash值,使用较短时间即可完成对数据的杂凑处理,同时具有较为理想的混乱与扩散性质,符合Hash函数的各项性能要求。A parallel Hash function based on coupled dynamic integer tent mapping is proposed. To deal with the problem of large data volume and slow processing speed, the MD6 algorithm framework was adopted, and the multi-core processor technology was used to process data in parallel. In the compression function, the bidirectional coupled mapping lattice model was used for diffusion, and the dynamic integer tent mapping was used to replace the traditional logic function. The experimental results show that the algorithm can obtain Hash values of different lengths according to the needs, and it can complete the Hash processing of the data in a short time. It has ideal chaos and diffusion properties, which meets the performance requirements of the Hash function.
