Abstract: The invention discloses trusted computing nodes (TCNs) configured to control their location and migration of applications run on virtual machines resident thereon. The invention allows a controlled use of cloud computing resources and virtual network functions by sensitive applications. This is achieved by embedding a secure processing unit (SPU) and a localization unit (LU) in the TCNs. The LU acquires GNSS signals and the TCN generates a secure location message comprising a secure ID and a locstamp of the TCN. A TCN Registry may be created by an operator of a collection of TCNs as a database of trust scores of the trusted computing nodes which will be used to control the allocation of tasks to said TCNs based, at least in part; on the trust scores. The trust scores may also be used directly by the other TCNs to allocate the tasks which they have control on.
