WiSec has been broadening its scope and seeks to present high quality research papers exploring security and privacy aspects of wireless communications, mobile networks, and their applications. Beyond the traditional Wisec staples of physical, link, and network layer security, we also welcome papers focusing on the security and privacy of mobile software platforms and the increasingly diverse range of mobile or wireless applications. The conference welcomes both theoretical as well as systems contributions. The proceedings will be published by the ACM.
