Abstract: An apparatus and method for detecting a change in electrical properties in a system is disclosed. Embodiments of the disclosure enable the detection of a change in electrical properties in a system by, in response to a load generated on a power delivery network power in at least part of the system, measuring noise induced in the power delivery network in response to the load. Based on the measured noise, a dynamic-response property of the power delivery network is determined and the dynamic-response property is compared to a stored reference dynamic-response property of the power delivery network based on a predetermined load. In the event of a difference between the dynamic-response property and the reference dynamic-response property, a response to the event is triggered to indicate tampering with the power delivery network.

Abstract: An apparatus and system for remote attestation of a power delivery network is disclosed. Embodiments of the disclosure enable remote attestation of the power delivery network by storing a trusted golden reference waveform in secure memory. The trusted golden reference waveform characterizes a power delivery network in response to a load generated on the power delivery network. A remote cloud server generates a server-generated remote attestation of the power delivery network by receiving an attestation packet from the power delivery network and verifying whether the attestation packet is consistent with an expected power delivery network identity.

Abstract: An apparatus comprises a plurality of redundant processing units to perform data processing redundantly in lockstep; common mode fault detection circuitry to detect an event indicative of a potential common mode fault affecting each of the plurality of redundant processing units; a memory shared between the plurality of redundant processing units; and memory checking circuitry to perform a memory scanning operation to scan at least part of the memory for errors; in which the memory checking circuitry performs the memory scanning operation in response to a common mode fault signal generated by the common mode fault detection circuitry indicating that the event indicative of a potential common mode fault has been detected.

Abstract: A data processing apparatus comprises branch prediction circuitry adapted to store at least one branch prediction state entry in relation to a stream of instructions, input circuitry to receive at least one input to generate a new branch prediction state entry, wherein the at least one input comprises a plurality of bits; and coding circuitry adapted to perform an encoding operation to encode at least some of the plurality of bits based on a value associated with a current execution environment in which the stream of instructions is being executed. This guards against potential attacks which exploit the ability for branch prediction entries trained by one execution environment to be used by another execution environment as a basis for branch predictions.

Abstract: Examples of the present disclosure relate to a method for anomaly response in a system on chip. The method comprises measuring a magnitude of a transient anomaly event in an operating condition of the system on chip. Based on the magnitude it is determined, for each of a plurality of components of the system on chip, an indication of susceptibility of that component to an anomaly event of the measured magnitude. Based on the determined indications of susceptibility for each of the plurality of components, an anomaly response action is determined. The method then comprises performing the anomaly response action.

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.
