At Rambus, we create cutting-edge semiconductor and IP products, providing industry-leading chips and silicon IP to make data faster and safer.
ARC4-IP-44 ARC4 Stream Cipher Accelerators
The ARC4-IP-44 (EIP-44) is IP for accelerating the ARC4 stream cipher algorithm (used for legacy SSL & IPsec) up to 5 Gbps @ 600MHz. Designed for fast integration, low gate count and full transforms, the ARC4-IP-44 accelerator provides a reliable and cost-effective embedded IP solution that is easy to integrate into high-speed crypto pipelines.

How the ARC4-IP-44 ARC4 Stream Cipher Accelerators work
The ARC4-IP-44 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 for any object sizes ranges up to 5 Gbps depending on the configuration and area. Gate count is about 7K to 32K gates depending on the configuration.
Rambus also offers the AES-IP-39 that supports AES modes and can be provided with countermeasures including ones against side-channel attacks and fault injection attacks.
