Many third-party utilities and applications that run on devices used in cellular networks keep track of our location data and share it. This vulnerability affects even the subscribers who use dumbphones. This thesis defines three location tracing attacks which are based on utilizing the background data and compares them with the most relevant known attacks. We have demonstrated that any attacker who knows two associated cells of a subscriber with adequate background data can deduce the intermediate cell IDs. Also, utilizing the Hidden Markov Model (HMM) increases the accuracy of an attack. In this dissertation, we introduced novel accuracy metrics for all the anticipated attacks and exploited these for detailed analysis of the threats in a real-life case, a 5G network. This work demonstrates improvements in the current privacy-preserving methods, including adaptation to 5G, and provides insights into preventing this location privacy breach. Various methods have been proposed to overcome these threats and preserve privacy against possible attacks based on this information. A friendly jamming (FJ) based solution, which offers efficient usage of resources, including computing power and energy, was introduced as a solution for these problems. However, one of the tradeoffs of FJ is its viability. Although some studies try to cope with this challenge, they are complicated and focus on old technologies. We propose a lightweight and flexible FJ scheme to address these challenges. We also demonstrate that our model has the same performance as one of the mentioned studies above in a more straightforward way.
