Broadcom and BlueSteel uBsec 5x0x
ubsec* at pci?
ubsec driver supports cards containing
any of the following chips:
- Bluesteel 5501
- The original chipset. 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 that also supports AES.
- Broadcom BCM5825
- Faster PCI Express or PCI-X version of the chip.
- Broadcom BCM5860
- IPsec/SSL Security Processor that is faster and has more features.
- Broadcom BCM5861
- Faster version of the BCM5860.
- Broadcom BCM5862
- Faster version of the BCM5861.
ubsec driver registers itself to
accelerate Triple-DES, MD5-HMAC, and SHA1-HMAC operations for
ipsec(4). The driver also supports acceleration of AES-CBC with the
BCM5823 or newer.
On all models except the Bluesteel 5501 and Broadcom 5801, the driver registers itself to provide random data to the random(4) subsystem.

ubsec device driver appeared in
The BCM5801 and BCM5802 have not actually been tested. Also, some of the newer chips support AES-CTR (AES Counter Mode) but it is not supported by the driver. The advanced SSL/TLS acceleration features of the BCM5860 or newer are not supported by the driver.
