Abstract-Recent advancements in micro-computing have provided an exponential increase in the capabilities of a wide range of devices and have allowed the implementation of complex mobile wireless sensor networks (mWSNs). Common batterypowered sensor nodes require security techniques that eliminate redundant processing overhead for resource conservation, without compromising the overall network performance. To address this issue, this paper presents USAS: Unpredictable Software-based Attestation Solution, a node compromise detection algorithm in mWSNs. USAS deploys dynamic node attestation chains to decrease checksum computation time by almost 48% for selective attested nodes. By decentralizing the network, the attestation is unpredictable, preventing malicious data injection. The performance of USAS is estimated in terms of node compromise detection rate.
A compromised node detection algorithm, based on code attestation, is proposed in REF and called Unpredictable Software-based Solution (USAS).
