As the need for information security increases in our everyday life, the job of encoding/decoding for secure information delivery becomes a critical issue in data network systems. High-speed data encoding for cryptography is required especially when sending a large amount of important data with high-speed transmission. In order to accomplish the procedure more efficiently, previous research focused on implementing existing algorithms using hardware accelerators. In this paper, we discuss and propose the FPGA implementation of the SEED block cipher algorithm, which is a Korean national industrial association standard for secured systems. Our implementation, which is written in Verilog HDL, is synthesized and tested on a Virtex-V XC5LX110T FPGA device. Our results show that the proposed fully pipelined design achieves high throughput and can support as high as 6.4 Gbps network speed. Compared to a full software implementation on the Intel Core 2 Duo 2.53 GHz processor, our implementation provides 34 times higher performance in terms of encoding/decoding throughput.
