A certified reference validation mechanism for the permission model of Android
Abstract
Android embodies security mechanisms at both OS and application level. In this platform application security is built primarily upon a system of permissions which specify restrictions on the operations a particular process can perform. The critical role of these security mechanisms makes them a prime target for (formal) verification. We present an idealized model of a reference monitor of the novel mechanisms of Android 6 (and further), where it is possible to grant permissions at run time. Using the programming language of the proof-assistant Coq we have developed a functional implementation of the reference validation mechanism and certified its correctness with respect to the specified reference monitor. Several properties concerning the permission model of Android 6 and its security mechanisms have been formally formulated and proved. Applying the program extraction mechanism provided by Coq we have also derived a certified Haskell prototype of the reference validation mechanism.
