Author claimed that it tooks about 1/2 hour on P100/32MB (due to limited smartcard bandwith :) to determine constant, stored in sim which he then used for sim simulation. You only need to know pin. (And as I remember, there are methods for old smartcards to determine pin :-) On Sat, Jan 26, 2002 at 09:16:02AM -0500, M Lister wrote: > > 2.
