Single-Chip Security Processor
GENERAL DESCRIP T ION
FE A T U R E S
The BCM5802 Security Processor provides industry-
standard IETF IPsec encryption and authentication
acceler a tion as we ll as I K E / SS L/TLS key setup
acceleration. Engine throughput is over 150 Mbps with
3DES strong encryption and MD5/SHA1 authentication
enabled. Sustained in-system performance with all
features enabled ranges up to 100 Mbps for crypto/
authentication acceleration and 30 1024-bit Diffie-Hellman
(180-bit exponent) key setups per second. The BCM5802
is ideal for cost-sensitive devices, including cable modem
access systems, xDSL access systems, T1/T3 line
security, and 10/100 Mbps ethernet interfaces.
The BCM5802 includes a built-in PCI 2.2 compliant
interface for easy hardware interfacing. It requires zero
external support components, enabling tremendous
system cost savings, and it features a streamlined high-
performance programming model for easy software
integration.
