SYSTEM, DEVICE, AND METHOD OF MANAGING TRUSTWORTHINESS OF ELECTRONIC DEVICES

Device, system, and method of managing trustworthiness of electronic devices. For example, an Internet of Things (IoT) device is able to transmit data to a recipient device. The recipient device operates as a querying device, and utilizes a query agent to query a trust-management server with regard to the trustworthiness of the IoT device. The trust-management server receives from the IoT device a set of values indicating various parameters of the IoT device. The trust-management server generates a trustworthiness report pertaining to the IoT device, and sends the report as a response to the trustworthiness query. Optionally, a caching agent caches copies of trustworthiness reports and provides to querying devices such previous reports, together with an indication of their freshness level.
