UBSEC(4)	       FreeBSD Kernel Interfaces Manual		      UBSEC(4)

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.conf(5):

	   ubsec_load="YES"

DESCRIPTION
     The ubsec driver supports cards containing	Broadcom and BlueSteel uBsec
     5x0x crypto accelerator chips.

     The ubsec driver registers	itself to accelerate DES, Triple-DES,
     MD5-HMAC, and SHA1-HMAC operations	for 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 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
			     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.  This is the chip
			     found on the Sun Crypto Accelerator 1000.

	   Broadcom BCM5822  Faster version of the BCM5820.

	   Broadcom BCM5823  A BCM5822 with AES	capability.

	   Broadcom BCM5825  Faster version of the BCM5823.

HISTORY
     The ubsec device driver appeared in OpenBSD 2.8.  The ubsec device	driver
     was imported to FreeBSD 5.0.

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