Abstract
Techniques for enforcing trust policies for payload data transmitted through a data provisioning layer include: receiving, by a node in the data provisioning layer, payload data to be delivered to a recipient; obtaining, by the node, a trust policy indicating multiple attributes used to determine trustworthiness of payloads; determining, by the node, a set of values of the attributes associated with the payload data; generating, by the node, a trustworthiness opinion based at least on the trust policy and the set of values of the attributes; transmitting, by the node, the payload data and the trustworthiness opinion via the data provisioning layer toward the recipient; computing, by the recipient, a trustworthiness metric associated with the payload data based at least on the trustworthiness opinion; and determining, by the recipient, an action to take with respect to the payload data based at least on the trustworthiness metric.
