Non-Interference and Erasure Policies for Java Card Bytecode.

Rene Rydhoff Hansen, Christian W. Probst

AbstractNon-interference is the property of a program not to leak any secret information. In this paper we propose a notion of non-interference for an abstract version of the Java Card bytecode language. Furthermore an information-flow analysis for verifying non-interference is developed and proved sound and correct with respect to the formal semantics of the language. The information-flow analysis can automatically verify the absence of leaks in a program, thus proving non-interference. Based on the definition of non-interference we propose a notion of simple erasure policies. These allow to statically check that confidential information is unavailable after a certain point---and that this unavailability is enforced by the system. This is a crucial requirement for systems like e-commerce or e-voting.
