A new and high-efficiency encryption and authentication algorithm, SMS4-GCM, based on cryptographic algorithm SMS4 and block cipher operating mode GCM is proposed. Design using full pipeline architecture and implementation on FPGA are presented in detail, and the results show that the maximal processing rate of SMS4-GCM can reach up to 22.248 Gbps which can meet the demands of high-speed network's applications.
