I believe smartcards (and trusted computing platforms too, btw) aim to solve
the following problem:
"How to enforce your own security policy in a hostile environment, not
under your own physical control?"
Examples:
- Smartcard: electronic purse: you cannot increase the amount on
your e-purse (unless reloading at the bank).
- Trusted computing: DRM: my content cannot be illegally copied on
your machine.
As soon as the environment is under your won physical control, software only
solutions suffice.
Regards,
Jaap-Henk
