Abstract
In one embodiment, the present disclosure is directed to a system for digital authentication. A device includes a second processor for security functionality. The second processor generates a public key and a private key, and uses the private key and to-be-signed signature data to generate digital signatures. The device transmits the public key and a first digital signature to the server. As part of subsequent communication, the device transmits the public key and a second digital signature to the server. Using the public key, the server validates the second digital signature to verify that the second digital signature is from the device or a user of the device, thereby verifying that the subsequent communication is from the device or the user of the device.
