Using Segment Number Parameter of Piecewise Linear Chaotic Map Construct Novel Hash Scheme
A novel keyed Hash function is presented based on the dynamic S-boxes.The proposed approach can give a chaotic Hash value by means of the lookup table of functions and chaotic dynamic S-box.Compared with the existing chaotic Hash functions,this method improves computational performance of Hash system by using the chaotic S-box substitution.Theoretical and experimental results show that the proposed method has not only strong one way property,sensitivity to initial conditions and chaotic systems parameters,but also high speed.
