Using PKI for security and authentication of control devices and their data

A method, executed by one or more computers, for real-time estimation of trustworthiness of data in a computer network, the method comprising:

• storing a trust score for each of a plurality of electronic device in the computer network, wherein each of the trust scores limits access to certain records or certain documents;
• provisioning a first and a second electronic devices by providing a unique identification, a digital identity token and a cryptographic key to each of the first and second electronic devices;
• attributing a new trust score to the second electronic device, by the first electronic device;
• increasing or decreasing the stored trust score for the second electronic device based on the new trust to generate a total trust score for the second electronic device;
• inviting the second electronic device by the first electronic device to establish a communication line with the first electronic device, when the total trust-score of the second electronic device is greater than a predetermined score;
• and
• establishing a secure communication line between the first electronic device and the second electronic device.
