摘要： At least one machine accessible medium having instructions stored thereon for authenticating a hardware device is provided. When executed by a processor, the instructions cause the processor to receive two or more device keys from a physically unclonable function (PUF) on the hardware device, generate a device identifier from the two or more device keys, obtain a device certificate from the hardware device, perform a verification of the device identifier, and provide a result of the device identifier verification. In a more specific embodiment, the instructions cause the processor to perform a verification of a digital signature in the device certificate and to provide a result of the digital signature verification. The hardware device may be rejected if at least one of the device identifier verification and the digital signature verification fails.

摘要： The output of a physically unclonable function (PUF) may be processed to reduce its size. The post-processing result is served as a device intrinsic unclonable identifier and is signed by the device manufacturer to create a certificate stored on board the same device that includes the physically unclonable function. This scheme may not require online verification and complex error correction on PUFs in some cases.

摘要： Dark-bit masking technologies for physically unclonable function (PUF) components are described. A computing system includes a processor core and a secure key manager component coupled to the processor core. The secure key manager includes the PUF component, and a dark-bit masking circuit coupled to the PUF component. The dark-bit masking circuit is to measure a PUF value of the PUF component multiple times during a dark-bit window to detect whether the PUF value of the PUF component is a dark bit. The dark bit indicates that the PUF value of the PUF component is unstable during the dark-bit window. The dark-bit masking circuit is to output the PUF value as an output PUF bit of the PUF component when the PUF value is not the dark bit and set the output PUF bit to be a specified value when the PUF value of the PUF component is the dark bit.
