Abstract
A device-bound certificate authority binds a certificate to one or more devices by including digital fingerprints of the devices in the certificate. A device only uses a device-bound certificate if the digital fingerprint of the device is included in the certificate and is verified. Thus, a certificate is only usable by one or more devices to which the certificate is explicitly bound. Such device-bound certificates can be used for various purposes served by certificates generally such as device driver authentication and authorization of access to secure content, for example.
