Abstract

The present disclosure provides a trusted processor configured to provide for the pairing of a subsystem leader and a subsystem follower, the trusted processor configured to: receive, from the subsystem leader, a subsystem leader identifier and a subsystem follower identifier; generate a leader pairing material transport key (PMTK); transmit the leader PMTK to the subsystem leader; and transmit a derived PMTK to the subsystem follower, wherein the derived PMTK is derived based on the received subsystem follower identifier and the leader PMTK; wherein the transmitted leader PMTK and the derived PMTK are configured to be used by the subsystem leader and the subsystem follower to securely authenticate each other and, based on this authentication, set up respective long term pairing keys for ongoing communication therebetween. The disclosure also provides for a corresponding subsystem comprising the subsystem leader and the subsystem follower.
