Welcome message from the D-SPAN 2013 chairs

As the organizing committee, it is our pleasure to present the proceedings of the 4th IEEE International Workshop on Data Security and PrivAcy in wireless Networks (D-SPAN), held on June 4, 2013, in Madrid, Spain. The goal of this one-day workshop, organized in conjunction with the 14th IEEE WoWMoM 2013, is to exchange cutting-edge ideas for securing the next-generation wireless networks, systems, and applications. D-SPAN covers a wide range of security-related topics, including security and privacy of data collection, transmission, storage, publishing, and sharing in wireless networks broadly defined such as cellular and mobile ad hoc networks (MANET), vehicular ad hoc networks (VANET), cognitive and sensor networks to applying data analytics techniques to address security and privacy challenges in these networks. D-SPAN provides a forum for academic and industry researchers to present research ideas that build bridges across three communities: wireless networks, databases, and security.
