Abstract
A method for providing a trusted communication link in a wireless network. A mobility management entity (MME) interface of a MME virtualized network function (VNF) receives a trusted communication request. A MME interface trustlet is allocated to execute in a trusted security zone of compute resources provided by a virtual computing environment in which the MME VNF executes. The MME interface trustlet establishes trusted signaling with two or more different VNFs provided by virtual servers executing in the virtual computing environment. The MME interface trustlet sends a trust token to the eNB to establish the trusted communication link from the eNB via a virtualized network function path through the virtual computing environment.
