Secure-IC's Securyzr(TM) SM4 Crypto Engine

Overview

The SM4 crypto engine includes a generic & scalable implementation of the SM4 algorithm which is the block cipher standard of China.

It is compliant with the GBT.32907-2016 specification and can support several cipher modes including authenticated encryption. It is portable to ASIC and any FPGA’s. This algorithm has been adopted in TPM2.0 of the Trust Computing Group (TCG) standard.

For other SM4 solutions, please see dedicated product sheets: SM4-XTS Multi-Booster (SCZ_IP_BA425) and SM4-GCM Multi-Booster (SCZ_IP_BA415).
