Location data collection at a societal scale is increasingly becoming common - examples of this are call and data detail records in telecommunication companies, GPS samples collected by car companies, and GPS samples from mobile devices in mapping companies (e.g., Google, Microsoft). Such large scale mobility datasets have applications in urban planning, network planning, surveillance, and real-time...
Cooperation between nodes is essential for the functionality of a mobile ad-hoc network (MANET). However, since the nodes in a MANET are generally resource limited, some nodes could refuse service to other nodes to conserve their resources, thereby exhibiting selfish behavior. Also, since a MANET is often deployed in uncontrolled environments, some nodes could be compromised by an adversary and directed...
Information flow analysis is a powerful technique for reasoning about the sensitive information exposed by a program during its execution. While past work has proposed information theoretic metrics (e.g., Shannon entropy, min-entropy, guessing entropy, etc.) to quantify such information leakage, we argue that some of these measures not only result in counter-intuitive measures of leakage, but also...
