BCM5802 ADDITIONAL FEATURES TO BCM5801
The BCM5802 adds a number of features as compared to the BCM5801. The notable additional features are:
Diffie-Hellman, RSA, and DSA key setup execution unit to accelerate the public key operations.
True random number generator (RNG) functional unit to generate secure private keys for Diffie-Hellman key exchanges
and DSA signatures.
1024-bit register files to hold the large public key data.
The BCM5802 is completely pin and register compatible with BCM5801, and is completely backwards register
compatible with the BCM5801.
OPTIMAL APPLICATION AREAS
The BCM5802 enables high-speed security support for a variety of cost-sensitive applications and markets, including no
compromise VPN support, secure telecommuting and remote access. Specific applications areas are as follows:
Secure telecommuting and SOHO access devices based on cable or xDSL modem
Secure enterprise T1 and T3 access devices
Secure LAN access devices
PC-based VPN accelerator boards
PROCESSING OVERVIEW
The BCM5802 security processor manages IPsec packets in the following stages:
1
Fetch command context and data via descriptors.
2
If packet is inbound, authenticate then decrypt in pipelined fashion.
3
If packet is outbound, encrypt then authenticate in pipelined fashion.
4
Write (via descriptors) output data and authentication codes if applicable.
The command, data descriptor, packet data and context data fetch phases are completely overlapped with engine
processing. Output packet data writeback is completely overlapped as well.
