The AES-IP-37 (EIP-37) is IP for accelerating the AES Key Wrap cipher algorithm (NIST-Key-Wrap & RFC3394) up to 6 Gbps. Designed for fast integration, low gate count and full transforms, the AES-IP-37 accelerator provides a reliable and cost-effective embedded IP solution that is easy to integrate into SoCs that need high speed key wrap and (key) storage or key import and export systems.
The AES-IP-37 is a family of the cryptographic library elements in the Rambus hardware IP library (formerly of Inside Secure). The accelerators include I/O registers, encryption and decryption cores, and the logic for feedback modes and key scheduling.
Sustained performance ranges from 1 to 6 Gbps depending on the configuration and area. Gate count is between 33K and 62K gates (excluding memory) depending on the configuration. Multiple AES-IP-37 cores can be cascaded.
Key wrap performance of the low gate count version is around 100K key wraps of unwraps (for 80-Byte key data), for the high end it is around 500K to 700K depending on frequency.
