The high level of performance and integration in the BCM5821 makes it ideal for highperformance embedded applications with footprint and power limitations. In addition to its high-performance public-key engines, the BCM5821 offers acceleration for symmetric key functions at increased performance rates. The BCM5821 supports bulk SSL encryption and authentication (ARC4, SSL-MAC-MD5/SHA-1) in-system performance at 300 Mbps and IPsec (3DES, HMAC-SHA-1) in-system performance at 470 Mbps. A true hardware random number generator on the BCM5821 is well suited for IV seeding and secret key generation. For SSL applications, a single BCM5821 can support 4000 SSL sessions per second, thus dramatically improving the response time of load balancers, Web switches, servers, and SSL appliances. For IKE applications, the BCM5821 can initiate 3000 VPN tunnels per second. The BCM5821 device's PCI interface makes it a perfect solution for all cost-sensitive security applications. Requiring no external components, the BCM5821 is ideal for embedded applications with strict board space and power requirements. Furthermore, performance of the BCM5821 can easily be scaled to increase both public-key and bulk payload 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. The 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 BCM5821 users a complete system solution. The BCM5821 SDK includes support for VxWorks, Linux and BSD.
