Secure-IC's Securyzr™ SM4-XTS Multi-Booster

Overview

The SM4-XTS Multi-Booster crypto engine includes a generic & scalable implementation of the SM4 algorithm (a block cipher specified by the OSCCA) making the solution ideal for high-end applications (including key, tweak, input and output registers and Galois field multiplier).

This crypto engine targets high-performance applications such as data storage and memory encryption. Thanks to its scalability, it can be tailored to reach the best trade-off between performances, area and technology.

Overview
The SM4-XTS crypto engine 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 throughput and features required by a specific application can be taken into account in order to select the most optimal and compact configuration.

For other SM4 solutions, please see dedicated product sheets: SM4 Standard Crypto Engine (SCZ_IP_BA419) and SM4-GCM Multi-Booster (SCZ_IP_BA415).
