Technical Program
For the final program, we accepted 11 papers out of 33 regular submissions. Each presentation will receive a time slot of 20 minutes for presentation and 5 minutes for discussion. Please help us by preparing your presentations accordingly. For the presentations, a projector will be available - please bring your own notebook. In order to foster intensive discussions, a final "discussion session" is scheduled to summarize the workshop presentations and to discuss further research ideas.

Key Management in Wireless Sensor Networks

Abstract [PDF]
Wireless sensor networks (WSNs) are being used in many new applications due to ease of deployment. These sensors are tiny devices with limited resources and all computing devices including wireless radio operate using battery power. Due to resource constraints, large size and lack of infrastructure support, providing secured communication in a WSN has become a critical issue. There are two approaches of asymmetric and symmetric key approaches. As asymmetric cryptography is very complicated, this talk provides an overview of nontrivial key distribution and management schemes in WSNs.
One of the efficient and applicable methods is to randomly pre-distribute and preload secret keys into sensor nodes. But it suffers from the node capture attack, in which the compromised key can be used to crack communications between non-compromised nodes. Based on random graph theory, symmetric matrix operation, or polynomial calculations, several key pre-distribution mechanisms have been discussed in the literature, each of them has relative advantages and limitations. Finally, we introduce an efficient pairwise key establishment and management which can support a large network with fewer preloaded keys in each sensor node. Better network resilience against node capture attack, lower computational cost and communication overhead can also be achieved. Efficient key management is still an open problem and more research efforts are needed to find a better security solution for WSNs.
