In this topic an analysis of RRC messages in 4G and 5G should be done. There exist several different kind of these messages with different functions and level of information content. The focus should lay on messages related to the connection release. The analysis should consider privacy and security aspects. After the theoretical review and analysis the practical part should focus on an attack. An implementation of one security and privacy aspect should be done as a proof-of-concept with Open Source hard- and software.

The following things are requested to be designed, implemented, and evaluated (most likely via proof-of-concept) in this thesis:
• Security and availability analysis of specific RRC messages
• Implementation of an attack
• Practical evaluation with testing of commercial smartphones

We will offer you:
• Initial literature
  - https://doi.org/10.14722/NDSS.2016.23236
• Smart working environment
• Deep contact to supervisors and a lot of discussions and knowledge exchange

A detailed description of the topics will be formulated with you in initial meetings. For sure, the report needs to be written based on the requirements of the universities, as well as a detailed documentation and handing over the complete project with all sources. Depending on the chosen thesis type the content will be adapted in its complexity.

In this topic an analysis of Broadcast messages in 4G and 5G should be done. There exist several different kind of these messages with different functions and level of information content. The analysis should consider privacy and security aspects. After the theoretical review and analysis the practical part should focus on one aspect of the findings. An implementation of one security and privacy aspect should be done as a proof-of-concept with Open Source hard- and software.
