• Manufacturer Part Number: bcm5805
• Description: Bcm5805 - Security Processor
• Manufacturer: Broadcom Corp.

The BCM5805 security processor integrates a high-performance 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 highly integrated BCM5805
security processor is an ideal solution for VPN-enabled networking
products such as SOHO routers and gateways, VPN appliances, access
concentrators, and network interface cards.
Accelerating bulk cryptographic functions (DES, 3DES, SHA-1, and
MD5) and public-key operations, the BCM5805 is a streamlined design
ideally suited for all cost-sensitive applications. Extensive hardware
support for processing intensive public-key operations minimizes the
user software required for IKE and SSL/TLS key negotiations.
The BCM5805 offers 200 Mbps of IPsec processing (3DES, HMAC-
SHA-1) performance and 180 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 BCM5805 is well
suited for IV seeding and secret key generation.
The BCM5805 device’s PCI interface makes it a perfect solution for all
cost-sensitive security applications. Requiring no external components,
the BCM5805 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 BCM5805 users a complete system solution.
Compatibility with OpenSSL and industry-standard IPSec software from
SSH Communications eases integration and reduces time-to-market.
