Abstract: Methods and systems for detection and prevention of exploitation of embedded devices. A sensing component is configured to detect a plurality of emanated analog signals and generate one or more synchronization events. The synchronization events are used to perform one or more attestation analyses, including execution attestation, integrity attestation, and control-flow reconstruction, the results of which may be used to generate security events.

Abstract: Methods of sensory input integrity attestation are provided. Artifacts included within devices under test inject a known noise signal into the output signal of one or more output devices that are detectable by one or more input devices (i.e., sensors) of an embedded device, and monitor the received input data. By comparing the received signal against the expected noise signal, attestation of the validity of sensory input data is possible. Such sensory input data attestation is capable either locally or using a remote attestation device with knowledge of the expected data stream.
