Design for high throughput SHA-1 hash function on FPGA

Abstract

In this paper, we propose SHA-1 architectures to achieve high-throughput hardware implementations. Two techniques such as loop unfolding and pre-processing were used for high-speed SHA-1 core design. The system is made of four sub-modules to increase throughput. Xilinx Virtex-6 FPGA is used for implementation. Implemented SHA-1 module achieves a throughput of 7.35 Gbps, and its behavior has been verified by connecting with Xilinx MicroBlaze soft processor.
