On the Interplay between TLS Certificates and QUIC Performance
Marcin Nawrocki, Pouyan Fotouhi Tehrani, Raphael Hiesgen +3
In this paper, we revisit the performance of the QUIC connection setup and relate the design choices for fast and secure connections to common Web deployments. We analyze over 1M W…
Delay-Tolerant ICN and Its Application to LoRa
Peter Kietzmann, Jose Alamos, Dirk Kutscher +2
Connecting long-range wireless networks to the Internet imposes challenges due to vastly longer round-trip-times (RTTs). In this paper, we present an ICN protocol framework that en…
Waiting for QUIC: Passive Measurements to Understand QUIC Deployments
Jonas Mücke, Marcin Nawrocki, Raphael Hiesgen +6
QUIC experiences a rapid adoption since its standardization in 2021, and hypergiants configure their infrastructure to optimize for QUIC performance. In this paper, we introduce a…
Usable Security for an IoT OS: Integrating the Zoo of Embedded Crypto Components Below a Common API
Lena Boeckmann, Peter Kietzmann, Leandro Lanzieri +2
IoT devices differ widely in crypto-supporting hardware, ranging from no hardware support to powerful accelerators supporting numerous of operations including protected key storage…
Securing name resolution in the IoT: DNS over CoAP
Martine S. Lenders, Christian Amsüss, Cenk Gündogan +3
In this paper, we present the design, implementation, and analysis of DNS over CoAP (DoC), a new proposal for secure and privacy-friendly name resolution of constrained IoT devices…
The Race to the Vulnerable: Measuring the Log4j Shell Incident
Raphael Hiesgen, Marcin Nawrocki, Thomas C. Schmidt +1
The critical remote-code-execution (RCE) Log4Shell is a severe vulnerability that was disclosed to the public on December 10, 2021. It exploits a bug in the wide-spread Log4j libra…
DSME-LoRa: Seamless Long Range Communication Between Arbitrary Nodes in the Constrained IoT
José Álamos, Peter Kietzmann, Thomas Schmidt +1
Long range radio communication is preferred in many IoT deployments as it avoids the complexity of multi-hop wireless networks. LoRa is a popular, energy-efficient wireless modulat…
Long-Range ICN for the IoT: Exploring a LoRa System Design
Peter Kietzmann, Jose Alamos, Dirk Kutscher +2
This paper presents LoRa-ICN, a comprehensive IoT networking system based on a common long-range communication layer (LoRa) combined with Information-Centric Networking (ICN) princ…
Secure and Authorized Client-to-Client Communication for LwM2M
Leandro Lanzieri, Peter Kietzmann, Thomas C. Schmidt +1
Constrained devices on the Internet of Things (IoT) continuously produce and consume data. LwM2M manages millions of these devices in a server-centric architecture, which challenge…
