• Manufacturer Part Number: bcm5812
• Description: Bcm5812 - Security Processor
• Manufacturer: Broadcom Corp.

The BCM5812 complements the CryptoNetX™ family of security
processors. Offering software compatibility with the BCM580X and
BCM582X products, the BCM5812 allows customers to support
performance from 50 Mbps to 1 Gbps with a common software platform.
The BCM5812 security processor is a fully integrated, cost-effective
cryptographic processor capable of performing 50 Mbps of IPsec (3DES,
HMAC-SHA-1) system throughput. The BCM5812 includes AES in its
cryptographic engine with support of key lengths up to 256 bits. In
addition to its full-featured symmetric key engine, the BCM5812 offers
public-key acceleration for IKE processing at the rate of 50 Diffie-
Hellman transactions per second. The BCM5812 security processor is an
ideal solution for cost-sensitive applications requiring hardware
acceleration with the latest cryptographic features.
The BCM5812 combines performance and cost optimization for
applications requiring hardware assist for CPU-intensive IPSec and IKE
processing. Accelerating bulk cryptographic functions (AES, 3DES,
SHA-1, and MD5) and public-key operations, the BCM5812 includes
extensive hardware support for processing intensive public-key
operations and minimizes the user software required for IKE and SSL/
TLS key negotiations.

A true hardware random number generator on the BCM5812 is well
suited for IV seeding and secret key generation.
The BCM5812 device’s PCI interface makes it a perfect solution for all
cost-sensitive security applications. Requiring no external components,
the BCM5812 is ideal for embedded applications with strict board space
and power requirements. Furthermore, performance of the BCM5812
can easily be scaled to increase both IPsec and public-key processing
performance.
Unlimited security association (SA) support via system memory and a
multi-threaded DMA engine utilize system memory to maximize
throughput in real-world applications. Able to prefetch packet contexts,
this 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 BCM5812 users a complete system solution. The
BCM5812 SDK includes support for VxWorks, Linux, and BSD.
