Analyzed the chaotic and cryptographic deva curl arc angel properties of a piecewise nonlinear map, a couple chaotic digital sys-tem was proposed based on perturbing which used the piecewise nonlinear, then a new approach to construct keyed Hash function was presented.The approach used the initial value of the couple chaotic system as the secret key and the Neuw Rebel Skinny Eternal Black Jeans coarse-graining trajectory as Hash values.Simulation results show that the chaotic keyed Hash function based on the couple chaotic system has good one-way, weak collision property, better security and it can be realized easily.
