.Sh NAME
|
|
.Nm ubsec
|
|
.Nd Broadcom and BlueSteel uBsec 5x0x crypto accelerator
|
|
.Sh SYNOPSIS
|
|
.Cd device ubsec
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver supports cards containing Broadcom and BlueSteel uBsec 5x0x
|
|
crypto accelerator chips.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver registers itself to accelerate DES, Triple-DES, MD5-HMAC,
|
|
and SHA1-HMAC operations for
|
|
.Xr ipsec 4
|
|
and
|
|
.Xr crypto 4 .
|
|
.Pp
|
|
On those models which contain a public key engine (almost all of the
|
|
more recent ones), this feature is registered with the
|
|
.Xr crypto 4
|
|
subsystem.
|
|
.Pp
|
|
On all models except the Bluesteel 5501 and Broadcom 5801, the driver
|
|
registers itself to provide random data to the
|
|
.Xr random 4
|
|
subsystem.
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver supports cards containing any of the following chips:
|
|
.Bl -tag -width "Broadcom BCM5822" -offset indent
|
|
.It 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.
|
|
.It Bluesteel 5601
|
|
A faster and fixed version of the original, with a random number
|
|
unit and large number engine added.
|
|
.It Broadcom BCM5801
|
|
A BCM5805 without public key engine or random number generator.
|
|
.It Broadcom BCM5802
|
|
A slower version of the BCM5805.
|
|
.It Broadcom BCM5805
|
|
Faster version of Bluesteel 5601.
|
|
.It Broadcom BCM5820
|
|
64 bit version of the chip, and significantly more advanced.
|
|
.It Broadcom BCM5821
|
|
Faster version of the BCM5820.
|
|
.It Broadcom BCM5822
|
|
Faster version of the BCM5820.
|
|
.It Broadcom BCM5823
|
|
A BCM5822 with AES capability.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
device driver appeared in
|
|
.Ox 2.8 .
|
|
The
|
|
.Nm
|
|
device driver was imported to
|
|
.Fx 5.0 .
|
|
.Sh 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.
