    Abstract: A method and authenticator for authenticating a device in a system using the electrical properties of the device is disclosed. Embodiments of the disclosure enable authentication by receiving a plurality of input seed values from a requestor. For each input seed value, load stimuli are generated to produce an electrical load sequence on a power delivery network powering at least part of the system. Noise induced in the power delivery network is measured in response to the electrical load sequence using one or more sensors located on the power delivery network. Based on the measured noise, a dynamic response property (magnitude and phase response as a function of frequency) of the power delivery network corresponding to a respective input seed value can be determined and returned to the requestor.

    Abstract: In one example, a method includes obtaining, by a data processing device, first secret data associated with a first user and corresponding to a first location of a remote resource. The method further includes generating, using the first secret data, a first uniform resource locator (URL) usable to obtain the first location, and accessing the first location using the first URL. The method further includes obtaining, in response to transfer of usage rights of the data processing device from the first user to a second user, second secret data associated with the second user and corresponding to a second location of the remote resource. The method further includes generating, using the second secret data, a second URL usable to obtain the second location, and accessing the second location using the second URL. The second location is inaccessible via the first URL. The first location is inaccessible via the second URL.

    Abstract: A device comprising: a processing element; a data store, coupled to the processing element, the data store comprising a non-volatile data store having a trusted region for trusted code and an untrusted region for untrusted code; a security component, coupled to the processing element and the data store, wherein the security component is configured to, in response to one of a power event occurring at the device and receiving a trigger signal, send a first signal to the processing element and the data store, and wherein the processing element is configured to execute trusted code in response to the first signal.
