Abstract
A method and system for determining the level of allowed communication between devices. By addition of one or more tamper-resistant proximity check server(s), round-trip time measurements to estimate the distance between the communication devices are performed in order to determine the amount of communication allowed between these devices. In one embodiment, a single tamper-resistant proximity server computes the distance between communication devices that are implemented as trusted applications on open platforms.
