ubsec
— Broadcom
and BlueSteel uBsec 5x0x crypto accelerator
ubsec* at pci? dev ? function ?
The ubsec
driver supports cards containing
any of the following chips:
The ubsec
driver registers itself to
accelerate DES, Triple-DES, MD5, SHA1, MD5-HMAC, and SHA1-HMAC operations
for opencrypto(9), and
thus for ipsec(4) and
crypto(4). The driver also
supports acceleration of AES-CBC with the BCM5823 or newer.
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 rnd(4) subsystem.
The ubsec
device driver appeared in
OpenBSD 2.8. The ubsec
device driver was imported to FreeBSD 5.0,
back-ported to FreeBSD 4.8, and subsequently
imported to NetBSD 2.0.
The BCM5801 and BCM5802 have not actually been tested.
