NAME
ubsec
- Broadcom and BlueSteel uBsec 5x0x crypto accelerator
SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
device crypto
device cryptodev
device ubsec
Alternatively, to load the driver as a
module at boot time, place the following line in
loader.conf5:
ubsec_load="YES"
DESCRIPTION
The
The
ipsec (4)
and
crypto (4).
On those models which contain a public key engine (almost all of the
more recent ones), this feature is registered with the
crypto (4)
subsystem.
On all models except the Bluesteel 5501 and Broadcom 5801, the driver
registers itself to provide random data to the
random (4)
subsystem.
HARDWARE
The
Bluesteel 5501
The original chipset, no longer made.
This extremely rare unit
was not very fast, lacked a 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 added.
Broadcom BCM5801
A BCM5805 without public key engine or random number generator.
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 more advanced.
Broadcom BCM5821
Faster version of the BCM5820.
Broadcom BCM5822
Faster version of the BCM5820.
Broadcom BCM5823
A BCM5822 with AES capability.

HISTORY
The
BUGS
The BCM5801 and BCM5802 have not actually been tested.
The AES capability of the BCM5823 is not yet supported; it is awaiting
public disclosure of programming information from Broadcom.
