All Silicon IP

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.

Benefits

The BA419 IP core is easily portable to ASIC and FPGA. It supports a wide range of applications on various technologies. The unique architecture enables a high level of flexibility.

The IP Core is also available in the crypto coprocessor (BA450) and the Root of Trust/HSM (BA470) from Silex Insight.

Applications
