Abstract
A trusted execution environment on a computing device within an enterprise, whether owned by the enterprise or the employee/user, allows invocation of trusted enterprise applications without hindering external or non-enterprise apps from running on the same computing device. Each of the trusted apps can interact with other trusted apps on the same enterprise computing device in a trusted manner such that other apps or untrusted network connections are prevented for access to the trusted apps. The computing device, however, also executes non enterprise applications which operate independently of the enterprise apps in the same address space using the same unmodified operating system as the enterprise apps on the computing device. The trusted execution environment therefore restricts interprocess communication to be only within the set of enterprise apps and also permits unimpeded operation of other apps under the same OTS (off the shelf) operating system.
