HMAC-IP-59 (EIP-59) is IP for accelerating the various single pass HMAC (FIPS-198-1) algorithms using secure hash integrity algorithms like MD5 (RFC1231), SHA-1 (FIPS-180-2), SHA-2 (FIPS-180-3/4) and SHA-3 (FIPS-202), up to 8 Gbps. Designed for fast integration, low gate count and full transforms, the HMAC-IP-59 accelerators provide a reliable and cost-effective embedded IP solution that is easy to integrate into high-speed crypto pipelines.
How the HMAC-IP-59 works
The HMAC-IP-59 is a family of the cryptographic library elements in the Rambus hardware IP library (formerly of Inside Secure). For example, the HMAC-IP-59 is the hash core embedded in the IPsec packet engines as well as the VaultIP root of trust cores providing support for MD5 and SHA based Hash and HMAC functions. The accelerators include I/O registers, encryption and decryption cores, and the logic for feedback modes and key scheduling.
Sustained performance for any object sizes ranges from 2 to 8 Gbps, depending on the configuration and area. Gate counts ranges from 23K to 95K gates depending on the configuration.
