The SM4-GCM is an extension of their AES-GCM high performance which support SM4 and AES in 1 signal IP Core while keeping the high throughput. This OSCCA compliant security IP is available as of today. SM4 is the first commercial cryptographic algorithm officially announced in China. Though SM4 was originally designed for data security and protection in WLAN, it demonstrates high application value in many other data transmission and protection scenarios.
