Abstract EN
Time-slotted channel hopping (TSCH), which can enable highly reliable and low-power wireless mesh networks, is the cornerstone of current industrial wireless standards.
In a TSCH network, all nodes must maintain high-precision synchronization.
If an adversary launches a time-synchronization attack on a TSCH network, the entire network communication system can be paralyzed.
Thus, time-synchronization security is a key problem in this network.
In this article, time synchronization is divided into single-hop pairwise, clusterwise, and three-level multihop according to the network scope.
We deeply analyze their security vulnerabilities due to the TSCH technology itself and its high-precision synchronization requirements and identify the specific attacks; then, we propose corresponding security countermeasures.
Finally, we built a test bed using 16 OpenMoteSTM nodes and the OpenWSN software to evaluate the performance of the proposed scheme.
The experimental results showed that serious security vulnerabilities exist in time-synchronization protocols, and the proposed countermeasures can successfully defend against the attacks.
