You need special control of the two lower, in normal smart cards unused contacts, which the Towitoko or any other normal IFD does not provide. > So, then, where to find a programmer? Either at the shops, where you can buy the Funcards or build one yourself. It is just an interface for RS-232 to the SPI interface used on Atmel controllers. > My problem is that after reading this Slashdot article here: > http://yro.slashdot.org/article.pl?sid=03/07/17/190232&mode=flat&tid=126 > > ...

Ok ... what you should know about the Funcard platform: 1) These are not secure controlers, but COTS controlers with nearly no security. (They do have internal lock bits for internal code and data, but the protection is nearly as good as what you can get from secure controlers.) 2) The Funcard has not big integer unit. So it can't do any RSA. So, what is SOSSE good for if there is not good platform? Learning and experimenting. SOSSE has been used for e.g.: 1) Analyzing DPA 2) Platform for implementing AES in a university lab course Mahlzeit endergone Zwiebeltuete _______________________________________________ Muscle mailing list [EMAIL PROTECTED] http://lists.musclecard.com/mailman/listinfo/muscle
