Apex: extending Android permission model and enforcement with user-defined runtime constraints

A policy enforcement framework for Android that allows a user to selectively grant permissions to applications as well as impose constraints on the usage of resources and an extended package installer that allows the user to set these constraints through an easy-to-use interface is presented.

Formal model and policy specification of usage control

A formal model and logical specification of UCON with an extension of Lamport's temporal logic of actions (TLA) is developed and shown the flexibility and expressive capability of this formal model by specifying the core models of U CON and some applications.
