Abstract: Techniques to facilitate verification of in-situ network telemetry data of data packet of data traffic of packet-switched networks are described herein. A technique described herein includes a network node obtaining a data packet of data traffic of a packet-switched network. The data packet includes an in-situ network telemetry block. The network node obtains telemetry data and cryptographic key. The cryptographic key confidentially identifies the network node. The node encrypts at least a portion of the telemetry data based on the cryptographic key to produce signed telemetry data and updates telemetry-data entry of the in-situ network telemetry block. The telemetry data and signed telemetry data is inserted into the telemetry-data entry. The node forwards the data packet with the updated telemetry-data entry to another network node of the packet-switched network.
