BCM5823 ETC, BCM5823 Datasheet - Page 2

• Manufacturer Part Number: BCM5823
• Description: SECURITY PROCESSOR
• Manufacturer: ETC

The BCM5823 security processor is a fully-integrated, high-
performance cryptographic processor capable of performing 500
Mbps of IPsec (3DES, HMAC-SHA-1) system throughput. The
BCM5823 includes AES in its cryptographic engine with
support of key lengths up to 256-bits. In addition to its high-
performance symmetric key engine, the BCM5823 offers public-
key acceleration for IKE processing at the rate of 400 Diffie-
Hellman transactions per second. The high level of performance
and integration in the BCM5823 makes it ideal for high-
performance embedded applications with footprint and power
limitations.
A true hardware random number generator on the BCM5823 is
well suited for IV seeding and secret key generation.
The BCM5823 is ideal for high-end and mid-range firewall and
VPN appliance applications. Able to scale to 1 Gbps with
multiple devices, the BCM5823 addresses a very broad range of
performance points. Utilizing a common software base,
customers can develop families of products with common
architectures and software platforms.

The BCM5823 device’s PCI interface makes it a perfect solution
for all cost-sensitive security applications. Requiring no external
components, the BCM5823 is ideal for embedded applications
with strict board space and power requirements. Furthermore,
performance of the BCM5823 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 utilizes system memory to
maximize throughput in real-world applications. Ability to pre-
fetch 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 BCM5823 users a complete
system solution. The BCM5823 SDK includes support for
