NAME    [Toc]    [Back]

     ubsec -- Broadcom and BlueSteel uBsec 5x0x crypto accelerator

SYNOPSIS    [Toc]    [Back]

     device ubsec

DESCRIPTION    [Toc]    [Back]

     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 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

	   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.

     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.

HISTORY    [Toc]    [Back]

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

BUGS    [Toc]    [Back]

     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.
