UBSEC(4) BSD Kernel Interfaces Manual UBSEC(4)
ubsec -- Broadcom and BlueSteel uBsec 5x0x crypto accelerator
ubsec* at pci?
The ubsec driver supports cards containing any of the following chips:
Bluesteel 5501 The original chipset, no longer made. This
extremely rare unit was not very fast, lacked an
RNG, and had a number of other bugs.
Bluesteel 5601 A faster and fixed version of the original, with
a random number unit and large number engine
Broadcom BCM5801 A BCM5805 without public key engine or random
Broadcom BCM5802 A slower version of the BCM5805.
Broadcom BCM5805 Faster version of Bluesteel 5601.
Broadcom BCM5820 64 bit version of the chip, and significantly
Broadcom BCM5821 Faster version of the BCM5820. This is the chip
found on the Sun Crypto Accelerator 1000.
Broadcom BCM5822 Faster version of the BCM5820.
Broadcom BCM5823 Faster version of the BCM5822 that also supports
Broadcom BCM5825 Faster PCI Express or PCI-X version of the chip.
Broadcom BCM5860 IPSec/SSL Security Processor that is faster and
has more features.
Broadcom BCM5861 Faster version of the BCM5860.
Broadcom BCM5862 Faster version of the BCM5861.
The ubsec driver registers itself to accelerate DES, Triple-DES,
MD5-HMAC, and SHA1-HMAC operations for ipsec(4). The driver also sup-
ports acceleration of AES-CBC with the BCM5823 or newer.
On all models except the Bluesteel 5501 and Broadcom 5801, the driver
registers itself to provide random data to the random(4) subsystem.

The ubsec device driver appeared in OpenBSD 2.8.
The BCM5801 and BCM5802 have not actually been tested. Also, some of the
newer chips support AES-CTR (AES Counter Mode) but it is not supported by
the driver. The advanced SSL/TLS acceleration features of the BCM5860 or
newer are not supported by the driver.
