Abstract
In one embodiment, the present disclosure is directed to a system for digital authentication, the system including a server and a device. The device includes a first processor and a second processor separate and distinct from the first processor and dedicated solely to security functionality. The second processor is programmed to generate a public key and a private key, and to use the private key and to-be-signed signature data to generate digital signatures, including a first digital signature. The device transmits the public key and the first digital signature to the server. The server stores the public key to uniquely identify the device or a user of the device in subsequent communications between the server and device.
