DESCRIPTION    [Toc]    [Back]

     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.
