AES ECB/CBC/CTR Accelerators

The AES-IP-36 (EIP-36) is IP for accelerating the AES symmetric cipher algorithm (FIPS-197), supporting ECB, CBC and CTR modes up to 12.8 Gbps @ 1GHz. Designed for fast integration, low gate count and full transforms, the AES-IP-36 accelerator provides a reliable and cost-effective embedded IP solution that is easy to integrate into high speed crypto pipelines.

How the AES-IP-36 AES ECB/CBC/CTR Accelerators work

The AES-IP-36 is a family of the cryptographic library elements in the Rambus hardware IP library (formerly of Inside Secure). For example, the AES-IP-36 is the cipher core embedded in all PacketEngine-IP-97/196/197 protocol-aware security engines. 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 2.5 to 12.8 Gbps depending on the configuration and area. Gate count is between 23K and 52K gates depending on the configuration. Multiple AES-IP-36 cores can be cascaded.

Rambus also offers the AES-IP-39 that supports more AES modes and can be provided with counter measures including ones against side-channel attacks and fault injection attacks.
