摘要： Several methods may be used to exploit the natural physical variations of sensors, to generate cryptographic physically unclonable functions (PUF) that may strengthen the cybersecurity of microelectronic systems. One method comprises extracting a stream of bits from the calibration table of each sensor to generate reference patterns, called PUF challenges, which can be stored in secure servers. The authentication of the sensor is positive when the data streams that are generated on demand, called PUF responses, match the challenges. To prevent a malicious party from generating responses, instructions may be added as part of the PUF challenges to define which parts of the calibration tables are to be used for response generation. Another method is based on differential sensors, one of them having the calibration module disconnected. The response to a physical or chemical signal of such a sensor may then be used to authenticate a specific pair of sensors.

摘要： An information processing device includes a processor configured to perform a diagnosis of hardware of the information processing device. The processor is configured to generate plural pieces of failure information. The plural pieces of failure information are classified into groups corresponding to different importance levels. The processor is configured to store the plural pieces of failure information in consecutive storage areas. The consecutive storage areas are divided into storage sections corresponding to the respective groups in order of importance level. The processor is configured to store first piece of failure information in a head of a second storage section in absence of free areas in first storage section. The first storage section is secured for a first group including the first piece of failure information. The second storage section is secured for a second group corresponding to a second importance level lower than the first importance level by one level.

The error framework may alternatively be implemented by a hardware component, such as a peripheral device for integration into a system. In one embodiment, an error framework of a microprocessor or a hardware component includes an error detection unit to capture an error within the hardware component; a state detection unit to capture error context information when the error is detected within the hardware component; an error event definition unit to define a unique error event representing a combination of the error and the error context information; and a configuration unit to define an error event response based on the unique error event. The error context information may include, for example, a known state of a system at the time the error occurs or a known state of the hardware component or microprocessor within which the error is detected at the time the error occurs.
