SNOW Crypto Accelerator

Overview

The EIP-46 cipher accelerators implement the specification of the 3GPP Confidentiality and Integrity Algorithms as specified by 3GPP and ETSI.

Designed for fast integration, low gate count and full transforms, the EIP-46 accelerator provides a reliable and cost-effective embedded IP solution that is easy to integrate into high speed SoCs for base stations or other equipment requiring 3GPP support.
