The tNAC (trusted Network Access Control) project aims to develop a NAC solution that is able to mitigate attacks that are based upon the Lying Endpoint Problem. It is funded by the German Federal Ministry of Education and Research. The Trust@FHH group participates in this project and is responsible for the integration of TNC and TPM features with a Trusted OS.
