.Dd May 16, 2009 .Dt UBSEC 4 .Os .Sh NAME .Nm ubsec .Nd Broadcom and BlueSteel uBsec 5x0x crypto accelerator .Sh SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "device crypto" .Cd "device cryptodev" .Cd "device ubsec" .Ed
p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent ubsec_load="YES" .Ed .Sh DESCRIPTION The .Nm driver supports cards containing Broadcom and BlueSteel uBsec 5x0x crypto accelerator chips.
p The .Nm driver registers itself to accelerate DES, Triple-DES, MD5-HMAC, and SHA1-HMAC operations for .Xr ipsec 4 and .Xr crypto 4 .
p On those models which contain a public key engine (almost all of the more recent ones), this feature is registered with the .Xr crypto 4 subsystem.
p On all models except the Bluesteel 5501 and Broadcom 5801, the driver registers itself to provide random data to the .Xr random 4 subsystem. .Sh HARDWARE The .Nm driver supports cards containing any of the following chips: l -tag -width "Broadcom BCM5822" -offset indent t 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. t Bluesteel 5601 A faster and fixed version of the original, with a random number unit and large number engine added. t Broadcom BCM5801 A BCM5805 without public key engine or random number generator. t Broadcom BCM5802 A slower version of the BCM5805. t Broadcom BCM5805 Faster version of Bluesteel 5601. t Broadcom BCM5820 64 bit version of the chip, and significantly more advanced. t Broadcom BCM5821 Faster version of the BCM5820. This is the chip found on the Sun Crypto Accelerator 1000. t Broadcom BCM5822 Faster version of the BCM5820. t Broadcom BCM5823 A BCM5822 with AES capability. t Broadcom BCM5825 Faster version of the BCM5823. .El .Sh SEE ALSO .Xr crypt 3 , .Xr crypto 4 , .Xr intro 4 , .Xr ipsec 4 , .Xr random 4 , .Xr crypto 9 .Sh HISTORY The .Nm device driver appeared in .Ox 2.8 . The .Nm device driver was imported to .Fx 5.0 . .Sh BUGS 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.
