Many scenarios require confidential communication and protection against active attackers. The way to establish trust between devices and authenticate these networks depends completely on the scenario. In Body Area Networks human biometrics can serve as a shared secret among devices. In real-time voice communication, the ZRTP protocol allows for interactive trust establishment by recognizing the peer's...
Cooperation between vehicles facilitates traffic management, road safety and infotainment applications. Cooperation, however, requires trust in the validity of the received information. In this paper, we tackle the challenge of securely exchanging parking spot availability information. Trust is crucial in order to support the decision of whether the querying vehicle should rely on the received information...
In Delay-Tolerant Networks (DTN), individual nodes with much higher rates of sending new bundles than average can degrade the delivery rate of other nodes substantially. They have a much higher impact on the overall network fairness than in traditional networks because of DTN — specific properties, such as decentralized design and the store-and-forward approach. Authenticated resource management schemes...
