Sensors that operate in an unattended, harsh or hostile environment are vulnerable to compromises because their low costs preclude the use of expensive tamper-resistant hardware. Thus, an adversary may reprogram them with malicious code to launch various insider attacks. Based on verifying the genuineness of the running program, we propose two distributed software-based attestation schemes that are well tailored for sensor networks. These schemes are based on a pseudorandom noise generation mechanism and a lightweight block-based pseudorandom memory traversal algorithm. Each node is loaded with pseudorandom noise in its empty program memory before deployment, and later on multiple neighbors of a suspicious node collaborate to verify the integrity of the code running on this node in a distributed manner. Our analysis and simulation show that these schemes achieve high detection rate even when multiple compromised neighbors collude in an attestation process.
