EviCheck: Digital Evidence for Android

We present EviCheck, a tool for the verification, certification and generation of lightweight fine-grained security policies for Android. It applies static analysis to check the conformance between an application and a given policy. A distinguishing feature of EviCheck is its ability to generate digital evidence: a certificate for the analysis algorithm asserting the conformance between the application and the policy. This certificate can be independently checked by another component (tool) to validate or refute the result of the analysis. The checking process is generally very efficient compared to certificate generation as experiments on 20,000 real-world applications show.
