Dear Mr. Klur,

I'm member of the CAFE consortium but I can not answer your question. As far as we know, the details of the Mondex protocols are still confidential (or only available under a non-disclosure license).

Oh, I see. Is this another one of those "we won't let you make sure that your money is safe with us, you'll just have to trust us" sort of things? Security through obscurity was never a very strong selling suit, especially to those who know that STO very likely hides a very weak encryption/authentication scheme.
