Abstract: Embodiments of the present invention address deficiencies of the art in respect to trusted platform module (TPM) unification in a trusted computing environment and provide a novel and non-obvious method, system and computer program product for trusted platform module data harmonization. In one embodiment of the invention, a TPM log harmonization method can include designating both a single master TPM for a master node among multiple nodes, and also a multiplicity of subsidiary TPMs for remaining ones of the nodes. The method further can include extending the single master TPM with a measurement representing a rendezvous operation for the nodes.

A secured TPM integration scheme towards smart embedded system based collaboration network
TL;DR: To achieve TPM integration, five protocols to orchestrate the distributed TPMs are proposed, including Synchronization Protocol (SYNP), Node Accessing Protocol (NAP), Crossing-Node Access Protocol (CNAP), Updating Protocol (UPDP) and Node-Removing protocol (NRP), and analysis on experimental results gives the guidance for appropriate use of these protocols.
