Overview

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.

Key features

  • Wide bus interface (32-bit data, 128-bit keys) or 32-bit register interface
  • Key sizes: 40 and 128 bits

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?
