Biography

Lea Schönberger (Graduate Student Member, IEEE) received the B.Sc. degree in computer science from the University of Münster, Germany, in 2014, and the M.Sc. degree in computer science from TU Dortmund University, Germany, in 2017, where she is currently pursuing the Ph.D. degree in computer science. Since September 2017, she is a Research Associate at TU Dortmund University, where she was a member of the Design Automation for Embedded Systems Group, Department of Computer Science, before she switched to a half-time position in the Databases and Information Systems Group, Department of Computer Science, along with a half-time position in the AG Embedded Systems, Department of Electrical Engineering and Information Technology, in August 2020...

Contract-Based Quality-of-Service Assurance in Dynamic Distributed Systems

Lea Schönberger;Susanne Graf;Selma Saidi;Dirk Ziegenbein;Arne Hamann

2022 Design, Automation & Test in Europe Conference & Exhibition (DATE)
Year: 2022 | Conference Paper |
To offer an infrastructure for autonomous systems offloading parts of their functionality, dynamic distributed systems must be able to satisfy non-functional quality-of-service (QoS) requirements. However, providing hard QoS guarantees without complex global verification that are satisfied even under uncertain conditions is very challenging. In this work, we propose a contract-based QoS assurance ...Show More

Towards an Increased Detection Sensitivity of Time-Delay Attacks on Precision Time Protocol

Lea Schönberger;Mohammad Hamad;Javier Velasquez Gomez;Sebastian Steinhorst;Selma Saidi

IEEE Access
Year: 2021 | Volume: 9 | Journal Article |
Cited by: Papers (4)
Precision time protocol (PTP) is one of the most widely used protocols for clock synchronization in packet-switched networks, on which, among others, the transaction synchronization of the stock markets relies. PTP was not standardized with security as a core requirement and is therefore vulnerable and attractive to manifold kinds of malicious attacks, such as time-delay attacks (TDAs). TDAs, in s...Show More

Priority-Preserving Optimization of Status Quo ID-Assignments in Controller Area Network

Sebastian Schwitalla;Lea Schönberger;Jian-Jia Chen

2020 Design, Automation & Test in Europe Conference & Exhibition (DATE)
Year: 2020 | Conference Paper |
Controller Area Network (CAN) is the prevailing solution for connecting multiple electronic control units (ECUs) in automotive systems. Every broadcast message on the bus is received by each bus participant and introduces computational overhead to the typically resource-constrained ECUs due to interrupt handling. To reduce this overhead, hardware message filters can be applied. However, since such...Show More

Design Optimization for Hardware-Based Message Filters in Broadcast Buses

Lea Schönberger;Georg von der Brüggen;Horst Schirmeier;Jian-Jia Chen

2019 Design, Automation & Test in Europe Conference & Exhibition (DATE)
Year: 2019 | Conference Paper |
Cited by: Papers (2)
In the field of automotive engineering, broadcast buses, e.g., Controller Area Network (CAN), are frequently used to connect multiple electronic control units (ECUs). Each message transmitted on such buses can be received by each single participant, but not all messages are relevant for every ECU. For this purpose, all incoming messages must be filtered in terms of relevance by either hardware or ...Show More

Do Nothing, But Carefully: Fault Tolerance with Timing Guarantees for Multiprocessor Systems Devoid of Online Adaptation

Georg von der Brüggen;Lea Schönberger;Jian-Jia Chen

2018 IEEE 23rd Pacific Rim International Symposium on Dependable Computing (PRDC)
Year: 2018 | Conference Paper |
Cited by: Papers (2)
Many practical real-time systems must be able to sustain several reliability threats induced by their physical environments that cause short-term abnormal system behavior, such as transient faults. To cope with this change of system behavior, online adaptions, which may introduce a high computation overhead, are performed in many cases to ensure the timeliness of the more important tasks while no ...Show More

Schedulability Analysis and Priority Assignment for Segmented Self-Suspending Tasks

Lea Schönberger;Wen-Hung Huang;Georg Von Der Brüggen;Kuan-Hsun Chen;Jian-Jia Chen

2018 IEEE 24th International Conference on Embedded and Real-Time Computing Systems and Applications (RTCSA)
Year: 2018 | Conference Paper |
Cited by: Papers (8)
Self-suspending behavior in real-time embedded systems can have a major and non-trivial negative impact on timing predictability. In this work, we investigate how to analyze the schedulability of segmented self-suspending task systems under a fixed-priority assignment. For this purpose, we introduce the multi-segment workload function as well as the maximum workload function in order to quantify t...Show More
