Security Processors Satisfy Next-Generation Networking, Wireless Apps

Networking and wireless applications, which are getting faster, need standalone security processors and new security algorithms that offer improved protection schemes and higher efficiency. Cavium Networks' Nitrox PX series of security processors fills that need. Target applications include integrated VPN/ firewall appliances, load balancers/L4+ switchers, 3G wireless infrastructure equipment, security gateways in telecom infrastructure, and storage-area network appliances.

The CN15xx and CN16xx high-performance standalone look-aside security processors offer scalable performance. Fully hardware and software compatible with the existing Nitrox Lite family, the CN15xx line supports the PCI-X bus. The CN16xx series supports the PCI Express serial interface bus. Their internal memory makes external chips unnecessary.

The Nitrox PX chips handle IPsec and SSL in wireless local-area and wide-area network applications. They support all the usual security encryption and authentication protocols and several new ones, including the SHA-2, AES-GCM (Galois Counter Mode), and Kasumi algorithms.

The top chips offer 17k max RSA 1024-bit exponent operations per second, 2.5-Gbit/s full inline IPsec throughput (w/AES + SHA-1), 2.5-Gbit/s full SSL record throughput (w/AES + MD5), and 2.5-Gbit/s Kasumi wireless processing.

The Nitrox PX chips come in a 256-PBGA package and consume 2 to 3 W. Prices range from $49 to $139 in 1000-unit lots. Samples will be available later in the fourth quarter with production quantities on hand in the first quarter of 2007. The Nitrox PX solutions additionally are available as fully operational accelerator boards.
