In this work we present a comprehensive formal specification of an
idealized formulation of Android?s permission model. Permissions in
Android are basically tags that developers declare in their applications,
more precisely in the so-called application manifest, to gain access
to sensitive resources. Several analyses have recently been carried
out concerning the security of the Android system. Few of them,
however, pay attention to the formal aspects of the permission enforcing
framework. We provide a complete and uniform formulation of several
security properties using the higher order logic of the Calculus of
Inductive Constructions and sketch the proofs that have been developed
and verified using the Coq proof assistant. We also analyze how the
changes introduced in the latest version of Android, that allows to
manage permissions at runtime, impact the presented model.
