Secure Execution Context Enforcement Framework Based on Activity Detection on Data and Applications Hosted on Smart Devices

A mechanism that takes into account the combination of security requirements from independent administrative entities over a set of interacting resources on a smart device requires the ability to provide some sort of execution context control. The proposed framework consists of an architecture and a policy model. The architecture detects different events and activities (i.e. user, system, applications) and based on them enforces applicable policies and constrains the execution context for a given set of resources. The policy model offers a method to dynamically create a secure execution context by combining different types of policies (e.g. access, usage, execution) issued by different entities on protected resources.
