The parallel computation in one-way hash function designing

In order to put the parallel one-way hash function into engineering, two designing models based on pipeline technology are proposed in this paper. The definition of one-way hash function is shown first, and the structure and limitation of the current hash functions are discussed afterward. By analyzing the difference between parallel computation on different platforms and classifying one-way hash functions on application basis, the possibility and method of parallel one-way hash function designing on different hardware platforms are described, two designing models are constructed for the parallel one-way hash function designing. Finally, some attentions for designing are proposed from the engineering angle. The pipeline models that proposed in this paper contact the theoretical rationality and the engineering application of parallel one-way hash function together, which can improve the practicality of parallel one-way hash function to a great extent.
