Resource-efficient implementation of Blue Midnight Wish-256 hash function on Xilinx FPGA platform

Abstract

This paper presents the design and analysis of an area efficient Blue Midnight Wish compression function with digest size of 256 bits (BMW-256) on FPGA platforms. The proposed architecture achieves significant improvements in system throughput with reduced area. We demonstrate the performance of the proposed BMW hash function core using VIRTEX 5 FPGA implementation. The new BMW hash function design allows for 16X speed up in performance while consuming significantly lower area than previously reported (i.e. just 445 slices).
