Privacy for Mobile Networks via Network Virtualization
Abstract
Today mobile devices have become powerful and ubiquitous. The conveniences afforded by these devices do not come without a cost, however. The use of mobile devices and mobile networks poses a significant risk to privacy. Four privacy requirements for mobile networks are identified: content privacy, identity privacy, location privacy, and authentication. This work focuses on content privacy. Two threats to content privacy are identified: the casual observer and the attacker. This work seeks to provide content privacy protection against the identified threats in mobile networks used by first responders. TwiddleNet, a mobile network designed for the data dissemination requirements of first responders, was used as a platform for implementation. A network virtualization technique was used in order to provide content privacy protection. This allows TwiddleNet users to share content on a per-group basis among virtual networks of user groups. It was found that this virtualization technique successfully provided content privacy protection from the threat of a casual observer, but not from an attacker. Providing adequate protections from the attacker threat requires more sophisticated measures and is left to future work.
