We describe an implementation of a Java program to perform automated
deduction in multi-modal logics on a Java smart card. The tight
space limits of Java smart cards make the implementation non-trivial. A
potential application is to ensure that applets
down-loaded off the internet conform to personalised security permissions
encoded on the Java card using a protocol based upon
multi-modal logic: that is, by using multi-modal logic to express notions
of permissions and obligations, we can turn the security
check into an on-board theorem proving task.
