Solutions and Tools for Secure Communication in Wireless Sensor Networks by Marco Tiloca
Security is considered one of the most important non functional requirements in Wireless Sensor Networks (WSNs) applications. It typically deals with protecting communication among network devices, as well as contrasting logical and physical attacks at different layers. Also, addressing security in WSNs is harder than usual, due to the presence of resource constrained devices, and the importance of limiting power consumption.
Some relevant security issues and recent solutions will be illustrated. First, we discuss secure communication in WSNs and its impact on network performance, considering both security services provided by the IEEE 802.15.4 standard, and a flexible application level approach based on software components. Second, we consider security services provided by the ZigBee technology, and how some deficiencies can be addressed. Third, an efficient and highly scalable key management scheme for secure group communication is presented. Then, we focus on the importance of quantitatively evaluating attack effects and their impact since during the network design phase, and how simulation tools can be useful in that sense. Finally, we consider selective jamming attack against TDMA-based WSNs, and how it can be effectively addressed.
Marco Tiloca is a postdoctoral research fellow at SICS in the Security Lab under the ERCIM Fellowship Programme. He received his Ph.D. Degree in Computer Engineering in May 2013 from the University of Pisa, Italy. His major contributions have covered secure communication in IEEE 802.15.4 and ZigBee networks, key management in secure group communication, and simulative evaluation of security attacks. Marco cooperated with Telecom Italia S.p.A. and the research center "E. Piaggio", and has been involved in the European Network of Excellence CONeT and the European Integrated Project PLANET.
