The BCM5820 integrates into a single 256-BGA package 4x–5x the
public-key performance of competing board level products at a fraction
of the cost. 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 Diffie-
Hellman 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 processing-
intensive public key operations minimizes the user software required for
IKE and SSL/TLS key negotiations. The BCM5820 is also software-
compatible with the BCM5805 E-commerce processor.
The BCM5820 E-commerce processor integrates the industry’s highest-
performance 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 board-
space-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.
