Abstract
Technologies for proving packet transit through uncompromised nodes are provided. An example method can include receiving a packet including one or more metadata elements generated based on security measurements from a plurality of nodes along a path of the packet; determining a validity of the one or more metadata elements based on a comparison of one or more values in the one or more metadata elements with one or more expected values calculated for the one or more metadata elements, one or more signatures in the one or more metadata elements, and/or timing information associated with the one or more metadata elements; and based on the one or more metadata elements, determining whether the packet traversed any compromised nodes along the path of the packet.
