Abstract

The new Gemplus smart card is based on the Java technology, embedding a virtual machine. The security policy uses mechanisms that are based on Java properties. This language provides segregation between applets. But due to the smart card constraints a byte code verifier can not be embedded. Moreover, in order to maximise the number of applets the byte code must be optimised. The security properties must be guaranteed despite of these optimisations. For this purpose, we propose an original manner to prove the equivalence between the interpreter of the JVM and our Java Card interpreter. It is based on the refinement and proof process of the B formal method.
