It's not clear to me whether the same restrictions apply to the use of the Tessera plug-in card.
Well, they are planning on selling the things to all comers as an encryption standard for all sorts of applications, so there are limits on how restrictive they can be.
It sounds, from what was posted here, like Blaze was able to feed sample LEAF's at his card until it accepted one. Is that correct?
Yes.
If so, apparently users of such cards have access to low-level functions which would allow this kind of trick to be used.
Yes.
Unless there is some way to get a supply of Clipper chips to allow you to make Clipper-compatible phones which still protect privacy, then all this theorizing is not too useful.
Clipper, Capstone, Tessera, etc, are, to my knowledge, interoperable implementations of the EES. Perry
