ubsec - Broadcom and BlueSteel uBsec 5x0x crypto accelerator
ubsec* at pci? dev ? function ?
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,
RNG, and had a number of other bugs.
Bluesteel 5601 A faster and fixed version of the
a random number unit and large number engine
Broadcom BCM5801 A BCM5805 without public key engine
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
Broadcom BCM5821 Faster version of the BCM5820. This
is the chip
found on the Sun Crypto Accelerator
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)
On all models except the Bluesteel 5501 and Broadcom 5801,
registers itself to provide random data to the random(4)
crypt(3), crypto(4), intro(4), ipsec(4), random(4), crypto(9)
The ubsec device driver appeared in OpenBSD 2.8.
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.
OpenBSD 3.6 June 10, 2000
