HoPP: Robust and Resilient Publish-Subscribe for an Information-Centric Internet of Things
IEEE Local Computer Networks

Zusammenfassung: This paper revisits NDN deployment in the IoT with a special focus on the interaction of sensors \em and actuators. Such scenarios require high responsiveness and limited control state at the constrained nodes. We argue that the NDN request-response pattern which prevents data push is vital for IoT networks. We contribute HoP-and-Pull (HoPP), a robust publish-subscribe scheme for typical IoT scenarios that targets IoT networks consisting of hundreds of resource constrained devices at intermittent connectivity. Our approach limits the FIB tables to a minimum and naturally supports mobility, temporary network partitioning, data aggregation and near real-time reactivity. We experimentally evaluate the protocol in a real-world deployment using the IoT-Lab testbed with varying numbers of constrained devices, each interconnected via IEEE 802.15.4 wireless LoWPANs. Implementations are built on CCN-lite with RIOT and support experiments using various single- and multi-hop scenarios.

Resilient Machine-to-Machine Communication for an Information-centric Industrial IoT
IEEE Local Computer Networks
Chicago, IL
Proc. of the 43rd Annual IEEE Conference on Local Computer Networks (LCN'18, Demo Session)
Verlag: IEEE Press, Piscataway, NJ, USA

Marker: TI-I

Zusammenfassung: In this demo, we showcase our lightweight Publish-Subscribe scheme HoPP based on the ICN flavour NDN. We deploy a multi-hop low-power and lossy network using constrained IoT devices operated by the RIOT operating system. An intelligent helmet is equipped with an O_2 gas sensor and periodically publishes gas readings to the remote cloud system of our industrial partner. On threshold excitation, the helmet notifies an operator and the network about an alarm situation. We show that all publishings and alarm notifications eventually arrive at the cloud despite of intermittent connectivity and manually induced network disruptions in our multi-hop scenario. A sniffer device provides a live packet trace to a web-based dashboard in order to visualize the topology maintenance and traffic flows.

The Rise of Certificate Transparency and Its Implications on the Internet Ecosystem
Internet Measurement Conference - IMC
Boston, MA
Proc. of ACM Internet Measurement Conference (IMC 2018) , Seite 343--349.
Association of the Computing Machinery
Verlag: ACM Digital Library, New York, NY, USA

Marker: TI-I

Zusammenfassung: In this paper, we analyze the evolution of Certificate Transparency (CT) over time and explore the implications of exposing certificate DNS names from the perspective of security and privacy. We find that certificates in CT logs have seen exponential growth. Website support for CT has also constantly increased, with now a majority of established connections supporting CT. With the increasing deployment of CT, there are also concerns of information leakage due to all certificates being visible in CT logs. To understand this threat, we introduce a CT honeypot and show that data from CT logs is being used to identify targets for scanning campaigns only minutes after certificate issuance. We present and evaluate a methodology to learn and validate new subdomains from the vast number of domains extracted from CT logged certificates.

HoPP: Publish--Subscribe for the Constrained IoT
Information-Centric Networking
Boston, MA
Proc. of 5th ACM Conference on Information-Centric Networking (ICN), Demo Session
ACM
Verlag: ACM Digital Library, New York, NY, USA

Marker: TI-I

Zusammenfassung: In this demo, we showcase our NDN based Publish--Subscribe scheme HoPP in a multi-hop low-power and lossy IoT deployment using constrained devices that operate RIOT. These devices publish temperature sensor readings and subscribe to fan control commands. We manually induce network disruptions to illustrate a seamless publisher and subscriber mobility with HoPP. A web-based dashboard highlights the network resilience and visualizes topology maintenance as well as traffic flows.

ICN-LoWPAN: Header Compression for the Constrained IoT
Information-Centric Networking
Boston, MA
Proc. of 5th ACM Conference on Information-Centric Networking (ICN), Poster Session
ACM
Verlag: ACM Digital Library, New York, NY, USA

Marker: TI-I

Zusammenfassung: This paper introduces stateless and stateful header compression to support small MTUs typical for low-power link layers in the Internet of Things. We evaluate our proposals on the multi-hop IoT-Lab testbed and show significant overhead reductions for NDN.
