cardT A P: Automated deduction on a smart card

We present the first implementation of a theorem prover which runs on a smart card. The prover is written in Java and implements a dual tableau calculus. Due to the limited resources available on current smart cards, the prover is restricted to propositional classical logic. It can be easily extended to full first-order logic. The potential applications for our prover lie within the context of security related functions based on trusted devices such as smart cards.
