CRYPT-IP-120 AES Crypto, SHA-2 Hash Core with DMA
The CRYPT-IP-120 combines local key storage, an AES cipher (AES-IP-39), a SHA-2 hash (HASH-IP-57) and DMA capability into an easy to integrate, silicon-proven package. Designed for fast integration into SoCs, and featuring low gate count and full transforms, the CRYPT-IP-120 DMA crypto engine provides a reliable and cost-effective embedded solution for high speed processing pipelines.

- 8 Gbps AES-256
- 4 Gbps SHA-256
CRYPT-120 Advantages
The CRYPT-IP-120 DMA crypto core provides hardware cryptographic algorithm implementations for optimal performance, user experience, battery lifetime and robust security.
- Significant performance boost compared to software execution on the host processor.
- Ability to store keys in an integrated RAM via DMA, and keep these inaccessible from (but usable by) the host/application.
The flexibility of the CRYPT-IP-120 architecture allows customization to individual requirements, including SNOW3G, Kasumi, AES-XTS and other basic IP modules.

Introduction to Side-Channel Attacks
Side-channel attacks conducted against electronic gear are relatively simple and inexpensive to execute. Such attacks include simple power analysis (SPA) and Differential Power Analysis (DPA). As all physical electronic systems routinely leak information, effective side-channel countermeasures should be implemented at the design stage to ensure protection of sensitive keys and data.
