Broadcom Introduces 4.8 Gbps IP Security Processor with AES Encryption, Enabling the World's Fastest Virtual Private Networks

9/25/2002 - Broadcom, the leading provider of integrated circuits enabling broadband communications, announced the Broadcom® BCM5841 Multi-Gigabit Security Processor, the industry's most versatile, highest performing 4.8 Gigabit per second (Gbps) IP security (IPSec) processor. The new, advanced IPSec processor delivers security encryption and authentication at multi-Gigabit speeds to eliminate VPN bottlenecks and degradation across the entire network infrastructure.

The BCM5841 incorporates full-featured Advanced Encryption Standard (AES) support with 256-bit key processing, patent-pending packet load balancing, and a variety of performance options sustaining throughputs of up to 4.8 Gbps. This enables corporations and service providers to utilize Virtual Private Networks (VPN) economically, while securely expanding their networks across geographic reaches to remote users and branch offices, using the most advanced standards-compliant security protocols at multi-Gigabit speeds.

"Optimized system performance in the security space is the most important requirement to our customers as well as to our customers' customers," said Devesh Garg, Senior Director of Broadcom's Security Line of Business. "As the pioneer of Gigabit security processors, Broadcom designed the new BCM5841 to be flexible enough to span multiple applications and address a variety of throughput requirements, making it an ideal complement to our overall technology portfolio."

By delivering up to 4.8 Gbps performance and by incorporating Broadcom's patent-pending packet load balancing, the BCM5841 enables security in high-bandwidth VPN equipment such as enterprise routers, firewalls, Layer 3+ switches, storage networks, access servers and VPN appliances. The packet load balancing feature allows networks to maintain full performance on a single flow and is designed to maintain its performance on all packet sizes without any performance degradation. As a result, the BCM5841 is able to handle processing-intensive workloads and the typical mix of traffic generated by leading-edge enterprise and carrier-class networks that transport voice, video and data, regardless of packet size or the number of connections.

The BCM5841 supports 256-bit key AES, the most recent U.S. Government-approved encryption algorithm necessary for IPSec-based equipment such as firewalls, VPN appliances, VPN-enabled routers and access devices. Support for 256-bit key AES, at 4.8 Gbps, provides the high-performance capabilities required to better secure confidential e-Commerce transactions and data transfers over the Internet.

The BCM5841 features flexible interfaces supporting either a POS-PHY level 3 (PL3) interface or a FIFO-configurable interface. The FIFO-configurable interface is used to seamlessly attach to Broadcom's SiByteTM family of broadband processors, including the BCM1250 and BCM1125, utilizing the FIFO interface of the network processing unit (NPU). The BCM5841 is also optimized to function as an IPSec co-processor that can computationally offload demanding cryptographic operations from a host protocol processor.

The BCM5841, the newest member of Broadcom's family of wirespeed CryptoNetXTM security processors, is the next-generation successor to Broadcom's well-established BCM5840 product - the world's first single-chip Gigabit security processor announced in January 2001. The new BCM5841 is backward-compatible with the BCM5840 Gigabit processor through a common software API, thus protecting existing customers' software investment while adding functionality and increased performance.

Utilizing the same common software API, both the new BCM5841 and its BCM5840 predecessor will be forward-compatible with Broadcom's next-generation of multi-Gigabit security solutions. Existing BCM5840 customers can easily upgrade to the new BCM5841 and its future successors, providing significant cost and time-to-market savings.

The addition of the BCM5841 to its security product family allows Broadcom to maintain its leadership position in the security market. The company's security processors now cover all essential performance ranges and support the growing number of applications requiring security. This sweeping coverage allows Broadcom to effectively address a variety of market segments with the industry's most cost-effective security solutions.

The BCM5841 is available in four different configurations - 4.8 Gbps throughput (BCM5841-48), 2.4 Gbps (BCM5841-24), 1.2 Gbps (BCM5841-12) and 0.6 Gbps (BCM5841-6). In all configurations, the chip supports IPSec bulk payload processing for all AES modes, including 128-, 192- and 256-bit AES-CBC and AES-CTR key length support. It also supports 3DES and DES symmetric algorithms, as well as HMAC-MD5 and HMAC-SHA-1 hash algorithms. The BCM5841 requires no external components or memory and has a power consumption of 2.8 Watts at 1.8V for 2.4 Gbps performance.

The BCM5841 Multi-Gigabit Security Processor is sampling today in all four configurations, with production quantities expected to be available in December 2002. The 0.18m CMOS chip features two package options: a 256-pin TBGA package (27 x 27 mm) and a 256-pin FPBGA package (17 x 17 mm). Interested customers should consult their authorized Broadcom representative for pricing options.
