AES key wrap family of accelerators.

Available in 3 configurations / performance grades.

Library element for storage solutions.

Product description

The AES-IP-37 is a family of the cryptographic library elements in Inside Secure’s HW IP library. The accelerators include I/O registers, encryption and decryption cores, and the logic for feedback modes and key scheduling.

Sustained performance ranges from 1Gbps to 6Gbps 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 80Byte key data), for the high end it is around 500K to 700K depending on frequency.
