     ubsec - Broadcom and BlueSteel uBsec 5x0x crypto accelerator

SYNOPSIS    [Toc]    [Back]

     ubsec* at pci? dev ? function ?

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 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  Faster version of the BCM5822.

     The ubsec driver registers itself to accelerate DES, TripleDES,
     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.

BUGS    [Toc]    [Back]

     The BCM5801 and BCM5802 have not actually been tested.   Also, some of the
     newer chips support AES but it is not supported by the driver.
