At Rambus, we create cutting-edge semiconductor and IP products, providing industry-leading chips and silicon IP to make data faster and safer.
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.
