Overview

The AES-IP-39 (EIP-39) is IP for accelerating the AES symmetric cipher algorithm (FIPS-197), supporting all NIST modes including ECB, CBC, CTR, CFB, OFB, CCM, GCM, CBC-MAC, CMAC, XTS, F8, F9 modes of operation up to 6.4 Gbps @ 1GHz. Designed for fast integration, low gate count and full transforms, the AES-IP-39 accelerator provides a reliable and cost-effective embedded IP solution that is easy to integrate into security modules needing versatile crypto.

How the AES-IP-39 AES “All Modes” Accelerators work

The AES-IP-39 is a family of the cryptographic library elements in the Rambus hardware IP library (formerly of Inside Secure). For example, the lightweight configuration of the AES-IP-39 is the cipher core embedded in all Vault-IP platform security engines as well as the Crypto-IP-120 DMA crypto core. 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 1 to 6.4 Gbps depending on the configuration and area. Gate count is between 27K and 45K gates depending on the configuration.

The AES-IP-39 can be provided with counter measures including ones against side-channel attacks and fault injection attacks.
