Although the security needs are well-recognized in this domain, it is still not fully understood how existing IP security protocols and architectures can be deployed. In this paper, we discuss the applicability and limitations of existing Internet protocols and security architectures in the context of the Internet of Things. First, we give an overview of the deployment model and general security needs. We then present challenges and requirements for IP-based security solutions and highlight specific technical limitations of standard IP security protocols. iotsec fileadmin/papers/2011/2011-heer-iot-challenges.pdf Online Springer

This attractive testing technique of unmodified software assists developers with concrete inputs and deterministic schedules to analyze erroneous program paths. Being able to handle complex systems' software, these tools only consider single software instances and not their distributed execution which forms the core of distributed systems. The step to symbolic distributed execution is however steep, posing two core challenges: (1) additional state growth and (2) the state intra-dependencies resulting from communication. In this paper, we present SDE—a novel approach enabling scalable symbolic execution of distributed systems. The key contribution of our work is two-fold. First, we generalize the problem space of SDE and develop an algorithm significantly eliminating redundant states during testing. The key idea is to benefit from the nodes' local communication minimizing the number of states representing the distributed execution. Second, we demonstrate the practical applicability of SDE in testing with three sensornet scenarios running Contiki OS. kleenet fileadmin/papers/2011/2011-06-icdcs-sasnauskas-sde.pdf Druck IEEE Computer Society

While such means are essential to overcome distances, using infrastructure services for location-based services may not be desirable. In this paper, we analyze a fully distributed variant of an ephemeral content sharing service, solely dependent on the mobile devices in the vicinity using principles of opportunistic networking. The net result is a best effort service for floating content in which: 1) information dissemination is geographically limited; 2) the lifetime and spreading of information depends on interested nodes being available; 3) content can only be created and distributed locally; and 4) content can only be added, but not explicitly deleted. First we present our system design and summarize its analytical modeling. Then we perform extensive evaluation for a map-based mobility model in downtown Helsinki to assess the operational range for floating content, which, at the same time also validate the analytical results obtained for a more abstract model of the system. https://www.comsys.rwth-aachen.de/fileadmin/papers/2011/2011-percom-vaegs-floatingcontent.pdf Online IEEE

A primary concern is the considerable amount of parallelization overhead imposed on the event handling routines of the simulation framework. Besides more complex event scheduling algorithms, the main sources of overhead are thread synchronization and locking of shared data structures. As a result, the overhead of parallelization may easily outweigh the benefits of parallelization in comparison to classic sequential simulation. We introduce two efficient event handling schemes based on our parallel-simulation extension Horizon for the OMNeT++ simulator.First, we present a \emph{push-based event handling scheme} to minimize the overhead of thread synchronization and locking. Second, we complement this scheme with a novel \emph{event scheduling algorithm} that significantly reduces the overhead of parallel event scheduling. Lastly, we prove the correctness of our scheduling algorithm. Our evaluation reveals a total reduction in the event handling overhead of up to 16x when combining both schemes. horizon fileadmin/papers/2011/2011-kunz-horizon-omnetworkshop.pdf Online ICST

This document specifies an extension for HIP that enables middleboxes to unambiguously verify the identities of hosts that communicate across them. This extension allows middleboxes to verify the liveness and freshness of a HIP association and, thus, to secure access control in middleboxes.
