NAME

lofn — Hifn 6500 crypto accelerator

SYNOPSIS

lofn* at pci?

DESCRIPTION

The lofn driver supports cards using the Hifn 6500 public key processor. This chip has both a random number generator and a large number processor. The random number generator provides random bits to the random(4) subsystem, while the large number processor registers with the crypto(4) subsystem to support modular exponentiation.
