WIP: Exploring DSME MAC for LoRa -- A System Integration and First Evaluation
José Álamos, Peter Kietzmann, Thomas C. Schmidt +1
LoRa is a popular wireless technology that enables low-throughput (bytes) long-range communication (km) at low energy consumption (mW). Its transmission, though, is on one side pro…
Transparent Forwarders: An Unnoticed Component of the Open DNS Infrastructure
Marcin Nawrocki, Maynard Koch, Thomas C. Schmidt +1
In this paper, we revisit the open DNS (ODNS) infrastructure and, for the first time, systematically measure and analyze transparent forwarders, DNS components that transparently r…
The Far Side of DNS Amplification: Tracing the DDoS Attack Ecosystem from the Internet Core
Marcin Nawrocki, Mattijs Jonker, Thomas C. Schmidt +1
In this paper, we shed new light on the DNS amplification ecosystem, by studying complementary data sources, bolstered by orthogonal methodologies. First, we introduce a passive at…
From the Beginning: Key Transitions in the First 15 Years of DNSSEC
Eric Osterweil, Pouyan Fotouhi Tehrani, Thomas C. Schmidt +1
When the global rollout of the DNS Security Extensions (DNSSEC) began in 2005, a first-of-its-kind trial started: The complexity of a core Internet protocol was magnified in favor…
PHiLIP on the HiL: Automated Multi-platform OS Testing with External Reference Devices
Kevin Weiss, Michel Rottleuthner, Thomas C. Schmidt +1
Developing an operating system (OS) for low-end embedded devices requires continuous adaptation to new hardware architectures and components, while serviceability of features needs…
Dynamic Clock Reconfiguration for the Constrained IoT and its Application to Energy-efficient Networking
Michel Rottleuthner, Thomas C. Schmidt, Matthias Wählisch
Clock configuration takes a key role in tuning constrained general-purpose microcontrollers for performance, timing accuracy, and energy efficiency. Configuring the underlying cloc…
