I got the info from the IBM patent web site. It's patent number 5,159,632
dated Sep. 17, 1991. The basic idea is Diffie-Hellman over GF(p^n) with p
being a Mersenne or Fermat prime so the calculations are faster. Note
that the patent uses a different form for the curve than is given by the
summing and doubling formulas. Technically, since that section is not in
the "claims" it doesn't matter. But I suspect a good lawyer could
demolish the whole thing if they look hard enough

Personally I'd clasify it as "obsolete" technology, but that's just my
opinion.

Patience, persistence, truth,
Dr. mike
