一种改进的宽管道Hash结构模型
An improved Hash model based on wide pipe structure
摘要
Abstract
A Hash function model of improved MD structure is proposed,which is based on wide pipe structure presented by Lucks on Asiacrypt Conference in 2005. Since the output width is large than the iteration width,the wide pipeline structure is easy to generate interior collision. The method of combining offline attack with fixed point attack is used by the attacker to form security threat for Hash function of wide pipe structure. Based on the wide pipe structure model,and in combination with the thought of random Hash,an improved Hash model of salt wide pipe(SWP)model is proposed. Proceeding from the aspect of collision resistivity,the fact that the security of the new SWP structure is better than that of the original SWP structure model is proved and verified. The structure can resist any offline attack.关键词
