Definition
Sensor code attestation is a way to verify the integrity of the code running on sensors through contactless software-based attestation.
Background
Sensors that operate in an unattended or hostile environment often suffer from break-in compromises, because their low costs do not allow the use of expensive tamper-resistant hardware. Besides the exposure of secret information (e.g., cryptographic keys), compromised sensors will often be reprogrammed with malicious code to launch all kinds of insider attacks.
Very desirably, if corrupted nodes could be identified and further revoked in a timely manner, the potential damages caused by them could be minimized. Intrusion detection mechanisms such as watchdog and reputation-based system have been proposed to detect abnormal nodes. However, these behavior-based detections are error-prone, because they rely on accurate...
