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
  • Low Speed, High Speed versions

Google, Quantum Attacks, and ECDSA: Why There’s No Need to Panic and Why Preparation Matters Now

Over the past several weeks, we’ve seen growing discussion across the industry about Google’s latest publications on quantum computing and cryptography. In some corners, those discussions have quickly escalated into claims that widely deployed elliptic curve cryptography (ECC), including ECDSA, is on the verge of collapse. Customers are understandably asking questions: Has ECDSA been broken? Are today’s systems suddenly at risk? Do migration timelines need to change?
