The BCM5820 device’s 32/64 33- to 66-MHz PCI interface makes it a perfect solution for add-in card applications for high performance E-commerce servers, load balancing, and web switching equipment. The BCM5820 offers full-duplex OC3 IPSec processing (310-Mbps 3DES, HMAC-SHA-1) performance, and in excess of 1250 DiffieHellman transactions per second (1024-bit public key, 160-bit private key), and 800 RSA private key signings per second. The BCM5820 is also ideal as a high performance VPN IKE coprocessor in Internet infrastructure aggregation equipment. The highly integrated BCM5820 E-commerce processor is the ideal solution for offloading compute-intensive SSL operations in E-commerce servers and networking products such as Web switches and load balancing devices. Extensive hardware support for processingintensive public key operations minimizes the user software required for IKE and SSL/TLS key negotiations. The BCM5820 is also softwarecompatible with the BCM5805 E-commerce processor. The BCM5820 E-commerce processor integrates the industry’s highestperformance single-chip public key processing unit, 200-Mbps ARC4 engine, true random number generator, high-performance IPSec engine (DES, 3DES, HMAC-SHA-1, HMAC-MD5), and 64/66 PCI interface all in a single chip configuration. Requiring no external components, the performance of the BCM5820 system can easily be scaled by adding more BCM5820 chips in boardspace-sensitive rack-mount equipment. An aggressive prefetch DMA eliminates the need for external memory and maximizes throughput under real-world conditions. API support through Broadcom’s Software Reference Library (SRL) for SSL and IPSec application software offers BCM5820 users a whole product solution. Compatibility with Open SSL, Microsoft IIS, iPlanet/ Netscape, PKCS-11, Novell®, and industry leading IPSec software from SSH Communications eases integration and reduces time-to-market.
