Given the open environment where sensor nodes are deployed, securing network programming is a challenging and important issue. Existing work addressing this issue either lacks the consideration on efficient or is not cost-efficient or dissemination-efficient. In this paper, we propose a novel scheme to disseminate code updates securely and efficiently. This scheme detects malicious nodes within the...
Wireless Sensor Network is a heterogeneous system combining tiny sensors with general purpose computing elements. Although many different routing protocols have been proposed for Wireless Sensor Network, most of which do not take security into account seriously. Routing attacks can have devastating effects on Wireless Sensor Network and present a major challenge when designing robust security mechanisms...
