Abstract
Clock synchronization is a critical issue in most wireless sensor network applications. Although the synchronization is well studied in last few years. Most of these synchronization protocols assume benign environments, but cannot survive malicious attacks in hostile environments, especially when there are compromised nodes. In this paper, we propose a secure synchronization protocol for sensor network. Our protocol combine the sender-receiver model and receiver-receiver model to verify the synchronization process between each synchronizing pair. The approach guarantees that normal nodes can synchronize their clocks to global clock even if each normal node has up to t colluding malicious neighbor nodes during synchronization phase.
