Cavium Networks Introduces the Broadest Security Solutions for WiMAX Base Stations and CPEs

nex-G Adopts Cavium Networks' New NITROX™ II WiMAX Solution in its 16 Sector Base Station to Support Current & Emerging WiMAX Security Standards at Multi-Gigabit speeds

Mountain View, CA, June 27, 2005 – Cavium Networks, a worldwide leader in security, network services and embedded processor solutions, today introduced the broadest security solutions for WiMAX based equipment ranging from Customer Premises Equipment (CPEs) to multi-sector Base Stations. The market leading Cavium Networks NITROX & NITROX II security processors provide 802.16-2004 compliant security solution for Base Stations requiring 75 Mbps to multi-Gbps performance. Additionally, the highly integrated MIPS32™ based Cavium Networks NITROX Soho Secure Communication Processors (SCP) provide the same support for CPEs requiring 64 Kbps to 20 Mbps performance. Given the high flexibility and programmability of these processor families, the security support is easily extendible to 802.16e, the mobile version of the WiMAX standard. The company also announced that nex-G, a designer, developer and manufacturer of carrier class wireless broadband solutions for the global market, is using NITROX II security processors in its Horizon Sixteen Sector WiMAX Base Station. This Base Station is a scalable solution, capable of supporting the world's high capacity networks for high-density deployment.

“We chose the NITROX II Security Processor for our Horizon WiMAX Sixteen Sector Base Station as it was the only product that met our performance and WiMAX security needs”, said Glen West, CTO of nex-G. “The security software and the support provided by Cavium Networks enabled us to rapidly and seamlessly integrate the NITROX II Security Processor into our system.”

WiMAX, a broadband wireless metropolitan area network (MAN) technology based on IEEE 802.16 and ETSI HiperMAN, can provide last mile broadband wireless access and can connect Wi-Fi hotspots to the Internet. Given that WiMAX data is transmitted over the air, the 802.16 standard requires a security sub-layer encrypting connections between Subscriber Station (CPE) and Base Station using the AES-CCM protocol. It also requires the usage of a client/server key management protocol based on X.509 digital certificates and RSA public-key encryption algorithm [PKCS #1]. Processing these algorithms on the CPU in the Base Station or CPE consumes valuable processing cycles thereby reducing application performance. The market leading NITROX, NITROX II and NITROX Soho product lines from Cavium Networks provide an optimal solution that offloads the security processing functionality at highly competitive prices.

New software for AES-CCM encryption protocol and WiMAX Public Key Management software is being released with the latest Software Development Kits for all NITROX and NITROX II Security Processors and NITROX Soho Processors from Cavium Networks.

The NITROX and NITROX II families of Security Processors have over two dozen members to target a wide range of price / performance points, for implementing WiMAX security in single or multi-sector Base Stations ranging in performance from 75 Mbps to multi-Gbps. The highly integrated NITROX Soho MIPS32 processor family includes nine members ranging in performance from 10 Mbps — 150 Mbps, that allow OEMs to build highly cost effective WiMAX CPEs and Base Stations. The NITROX Soho Processors integrate a MIPS32™ Processor with 16KB Instruction & Data Caches, powerful security engines, 3 x 10/100 Ethernet MACs, 32Bit PCI interfaces, and a range of General Purpose I/Os.

In addition to the security algorithms required by the 802.16-2004 specification, each of the product families supports a wide variety of other algorithms. For symmetric encryption, AES-256 (CTR, CBC, XCBC, ECB), DES, 3DES and ARC4 algorithms are supported. RSA and Diffie-Hellman algorithms are included for asymmetric encryption. SHA-1 and MD5 hash algorithms are also supported. For more information, please visit
