Bachelor Thesis – Development and implementation of a secure WLAN concept
This thesis focuses on the development and deployment of a secure WLAN solution for multiple establishments. Various encryption techniques, authentication, and authorization mechanisms were analyzed to determine the most effective approach to ensuring network security. After designing the WLAN security concept, a pilot project was carried out at a selected establishment, where the solution was implemented and thoroughly tested through performance evaluations.
Master Thesis – Analysis, Implementation and Optimization of an End-2-End Security Concept for the Internet of Things in an Industry 4.0 Scenario
This thesis addresses the challenge of securing communication in Industry 4.0 environments, where computational devices communicate over potentially insecure channels, such as cellular radio. While existing solutions often rely on transport layer encryption, this approach does not offer end-to-end security across multiple untrusted hosts.
The thesis designs and evaluates end-to-end encryption mechanisms for constrained IoT devices, using protocols such as CoAP, MQTT, MQTT-SN, and WebSocket. The work was demonstrated on Intel's Quark™ SE Microcontroller, which provided the necessary hardware environment. Through this evaluation, the most suitable encryption method was identified and implemented across the selected protocols.
The results confirmed that end-to-end encryption can be effectively implemented without significantly affecting protocol performance, though scalability issues arose with increasing numbers of participants due to communication and computation overhead.
