The BCM5823 security processor is a fully-integrated, highperformance 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 highperformance symmetric key engine, the BCM5823 offers publickey acceleration for IKE processing at the rate of 400 DiffieHellman transactions per second. The high level of performance and integration in the BCM5823 makes it ideal for highperformance 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 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 BCM5823 users a complete system solution. The BCM5823 SDK includes support for VxWorks(R), LinuxTM and BSD.
