Overview

The SNOW-IP-46 (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 SNOW-IP-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.

How the SNOW-IP-46 3GPP SNOW 3G Accelerators work

The SNOW-IP-46 is a family of the cryptographic library elements in the Rambus hardware IP library (formerly of Inside Secure). For example, the SNOW-IP-46 is the cipher core embedded in some 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 4 to 30 Gbps depending on the configuration, area and frequency. Gate count is 20K to 40K gates depending on the configuration. Supported modes: UEA2, UIA2, 128-EEA1 and 128-EIA1

Key features

  • Wide bus interface (32-bit data, 128-bit keys) or 32-bit register interface
  • Includes key scheduling hardware
  • Supported modes: UEA2, UIA2, 128-EEA1 and 128-EIA1
  • Fully synchronous design
