Does anyone know how the enabling of Fortezza LEAF suppression works? Since you
have to return the cards to the vendor so the LEAF suppression feature can be
added, it looks like there's an uploadable firmware patch available which would
turn off the GAK on any Fortezza card. I'd guess it's done via a signed upload
of new firmware to the card, but the fact that such a capability even exists,
and appears to work back to the very first cards (one of the vendor docs even
states that "the suppression of the LEAF has been rather easy"), is interesting.
Had Clipper/whatever taken off, it would have been a simple matter to disable
GAK in the government versions and leave the GAK'd ones for the masses.
