• Manufacturer Part Number: bcm5802
• Description: Bcm5802 - Security Processor
• Manufacturer: Broadcom Corp.

The BCM5802 security processor integrates Broadcom’s IPSec engine
(DES, 3DES, HMAC-SHA-1, HMAC-MD5), public-key processor, true
random number generator, PCI interface, and context buffer memory
onto a single chip. The BCM5802 security processor is an ideal solution
for DSL modems and VPN-enabled networking products such as SOHO
routers, gateways, and VPN appliances.
The BCM5802 combines performance and cost optimization for
applications requiring hardware assist for MIPS-intensive IPSec and
IKE processing. Accelerating bulk cryptographic functions (DES,
3DES, SHA-1, and MD5) and public-key operations, the BCM5802
includes extensive hardware support for processing intensive public-key
operations and minimizes the user software required for IKE and SSL/
TLS key negotiations.
The BCM5802 provides 100-Mbps performance and in excess of 30
Diffie-Hellman key exchanges per second (1024-bit public key, 180-bit
private key). IPSec performance is measured “in-system” on outbound
packets, with new security associations per packet.

A true hardware random number generator on the BCM5802 is well
suited for IV seeding and secret key generation.
The BCM5802 device’s PCI interface makes it a perfect solution for all
cost-sensitive security applications. Requiring no external components,
the BCM5802 is ideal for add-in card applications requiring IPSec
acceleration. 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.
Application program interface (API) support through Broadcom’s
Software Reference Library (SRL) for IPSec and SSL application
software offers BCM5802 users a complete system solution.
Compatibility with OpenSSL and industry-standard IPSec software from
SSH Communications eases integration and reduces time-to-market.
