Abstract

We consider the problem of enforcing information flow policies in Xml manipulating programs such as Web services and business processes implemented in current workflow languages. We propose a runtime monitor that can enforce the secrecy of freely chosen subtrees of the data throughout the execution. The key idea is to apply a generalized constant propagation for computing the public effect of branching constructs whose conditions may depend on the secret. This allows for a better precision than runtime monitors which rely on tainting of variables or nodes alone. We demonstrate our approach for a minimalistic tree manipulating programming language and prove its correctness w.r.t. the concrete semantics of programs.
