Abstract
A system, node and wireless device are provided. An intermediate node is provided that includes processing circuitry configured to: receive a packet where the packet includes metadata associated with first input data of a first node, first output data of the first node, a first PC signature and a public cryptographic key associated with the first node, verify that the first PC signature corresponds to a process that led from the first input data to the first output data using the public cryptographic key, verify a link between first node and the intermediate node by comparing the received packet and the first output data, and determine whether to perform at least one service function on the packet based at least in part on the verification of the first PC signature and the verification of the link between the first node and the intermediate node.
