Trust policies for a data provisioning layer

One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving, by a first node in a data provisioning layer, payload data to be delivered to a recipient;
• obtaining, by the first node, a trust policy indicating a plurality of attributes used to determine trustworthiness of payloads;
• determining, by the first node, a first set of values of the plurality of attributes associated with the payload data;
• generating, by the first node, a first trustworthiness opinion based at least on the trust policy and the first set of values of the plurality of attributes;
• and
• transmitting, by the first node, the payload data and the first trustworthiness opinion via the data provisioning layer toward the recipient.

One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving, by a recipient in a data provisioning layer, payload data and a trustworthiness opinion associated with the payload data;
• obtaining, by the recipient, a trust policy used to determine trustworthiness of payloads;
• computing, by the recipient, a trustworthiness metric associated with the payload data based at least on the trust policy and 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.
