• Manufacturer Part Number: bcm5821
• Description: Bcm5821 - Super E-commerce Processor
• Manufacturer: Broadcom Corp.

The BCM5821 Super E-commerce processor is a high-performance
public-key processor, able to perform over 4000 SSL/TLS sessions per
second and 3000 IKE negotiations per second. The high level of
performance and integration in the BCM5821 makes it ideal for high-
performance embedded applications with footprint and power
limitations.
In addition to its high-performance public-key engines, the BCM5821
offers acceleration for symmetric key functions at increased
performance rates. The BCM5821 supports bulk SSL encryption and
authentication (ARC4, SSL-MAC-MD5/SHA-1) in-system performance
at 300 Mbps and IPsec (3DES, HMAC-SHA-1) in-system performance
at 470 Mbps.
A true hardware random number generator on the BCM5821 is well
suited for IV seeding and secret key generation.
For SSL applications, a single BCM5821 can support 4000 SSL sessions
per second, thus dramatically improving the response time of load
balancers, Web switches, servers, and SSL appliances. For IKE
applications, the BCM5821 can initiate 3000 VPN tunnels per second.

The BCM5821 device’s PCI interface makes it a perfect solution for all
cost-sensitive security applications. Requiring no external components,
the BCM5821 is ideal for embedded applications with strict board space
and power requirements. Furthermore, performance of the BCM5821
can easily be scaled to increase both public-key and bulk payload
processing performance.
Unlimited security association (SA) support via system memory and a
multi-threaded DMA engine utilizes system memory to maximize
throughput in real-world applications. The ability to prefetch packet
contexts minimizes the performance degradation when processing small
packets. Concurrent public-key and bulk payload processing minimizes
latency and improves system performance dramatically.
Application program interface (API) support through Broadcom’s
Software Reference Library (SRL) for IPSec and SSL application
software offers BCM5821 users a complete system solution. The
BCM5821 SDK includes support for VxWorks, Linux and BSD.
