Designing power analysis resistant and high performance block cipher coprocessor using WDDL and wave-pipelining

Abstract

Novel design method and design flow of block cipher co-processor is presented based on the WDDL (Wave Dynamic Differential Logic) and Wave-Pipelining techniques. This design flow utilized the current commercially available EDA (Electronic Design Automatic) tools to a large degree. The WDDL and wave-pipelining based coprocessor not only resists power analysis, but also achieves high performance and low power consumption in nature. According to the design flow, this paper implements a DES coprocessor. The simulation results show that the novel design method does achieve high performance, low power consumption and power analysis resistant ability at the cost of chip area. © Springer-Verlag Berlin Heidelberg 2006.
