ARC International Announces Security Software for Embedded Networking Applications

IPShield™ Software Provides Privacy, Integrity and Authenticity, for Motorola, IBM, ARM and MIPS Processor Applications

San Jose, Calif., August 18, 2003 — ARC International (LSE: ARK), a world leader in user-customizable processors, silicon peripheral IP, real-time operating system and development tools for embedded system design, today unveiled its IPShield™ software, an Internet security solution providing embedded designers the ability to build security into their network-connected systems. Intended for such applications as small office/home office (SOHO) routers, xDSL/cable modems and security equipment, current versions of the IPShield software are compliant with Internet engineering task force (IETF) standards, including IPSec and Internet key exchange (IKE), and support a variety of security algorithms. The IPShield software is tightly integrated with ARC’s own compact, high-performance RTCS TCP/IP networking stack, so embedded developers can easily and cost-effectively incorporate strong, interoperable security features into their networking applications. The IPShield software is intended for designers wanting to incorporate IPSec software functions within their applications.

“With the amount of sensitive data being transmitted across today’s IP network, security is rapidly becoming a required feature in all classes of network-connected embedded devices. With our IPShield software, we have developed a security solution that provides the privacy, integrity and authenticity that addresses this growing demand,” said Andy Haines, senior vice president of marketing at ARC. “In addition, ARC is dedicated to providing an off-the-shelf security solution for hardware-accelerated encryption of network traffic, so developers can take advantage of the hardware security engine to achieve optimal performance for their designs.”

The IPShield software, a part of the networking family of ARC software products for embedded system developers, enhances the capabilities of embedded networking applications by providing a standard platform for securing networks with encrypted tunnels over the Internet. The software supports a variety of encryption and hashing algorithms such as DES, 3DES, MD5 and SHA. It allows for chained transforms, nested tunnel and replay-attack preventions against packet analysis during data transfer.

The IPShield software code can be ported to proprietary hardware encryption accelerators and user-specific instructions to enable designers to quickly develop secure network applications over a broad spectrum of embedded devices. The IPShield software is tightly integrated with an RTCS TCP/IP stack, so it can be incorporated on any platform supported by RTCS, such as the ARC ARCtangent™, ARM®, MIPSâ, Motorola® ColdFire® and Motorola/IBM PowerPC® architectures.

Pricing and Availability

The IPShield software is shipping today with pricing starting at $30,000 for a single product license.
