That sounds really interesting. I've looked at their website
http://www.sinosun.com.cn , but it does not contain much more
information. Anyway, "serial interface in conformance to
ISO 7816 Standard" sounds a little bit strange to me without
giving further details. Does not say anything about APDUs - maybe
they refer only to electrical characteristics. This could mean,
that a modified smartcard reader firmware (which allows sending
not only APDUs, but also TPM commands according to the published
TCG specs) could be used to access the chip.

So far, I'm not aware of any APDU standards from TCG. On the other
side, putting TPM commands in ISO7816 APDUs could work. The question
remains, if (or in which scenario) a smartcard-TPM would really make
sense, because it is no longer fixed to a specific platform. In this
case, I can see no real advantage compared to existing smartcards.

If you get further information about this SSX35 chip, it would ne nice
if you post them here or notify me.
