Yes, there is another approach to secure channels beside classical asymmetric/symmetric Crypto: Physical Layer Security. Physical Layer Security (PHYSEC) is a rich area and a very interesting approach, which combines Coding Theory, Networking, Game Theory and Cryptography. A PHYSEC based system is able to solve the problems of key-management- and key-establishment. Therefore, it represents a very attractive approach and it is a very new mechanism. However, our team (combining researchers from EMSEC and INFSEC as well as engineers from PHYSEC GmbH [1]) is the first one with a fully capable demonstrator and has leading experience in this topic.

In this Master’s thesis we want to address security mechanisms on the physical layer to foster new applications for the Internet of Things (IoT). The student's task is to evaluate the Physical Layer Security approach for LTE. For that the student implements an LTE PHYSEC framework using already existing software components like srsLTE [2] and/or OpenAirInterface [3]. It should be analyzed how LTE can be used for key-management and establishment. Good C and C++ programming skills are required; knowledge about signal processing and Software Defined Radio (SDR) is preferable.
