摘要
A client device is fabricated using a semiconductor fabrication process. One or more uncontrollable random physical processes in the semiconductor fabrication process can cause small differences between the client device and other client devices. When the client device is presented with a challenge from a server device, the client device generates a random response that depends on its physical properties. The server device stores this random response as a part of a virtual PUF circuitry storage device having other random responses from the other client devices. The server device uses the random response of the client device stored in the virtual PUF circuitry storage device for one or more encryption algorithms to encrypt information to be provided to the client device.
