There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract: The objective of the proposed research is to identify security vulnerabilities in LTE/LTE-A networks and devise policies that can help the network combat smart jamming attacks autonomously. LTE/LTE-A networks provide advanced data, Voice over IP (VoIP), multimedia, and location-based services to millions of subscribers around the world. Lately, it has been suggested to utilize commercially and privately-owned LTE/LTE-A networks for mission-critical applications like public safety, smart grid and military communications. Although LTE/LTE-A air interface provides ease of accessibility, flexibility, mobility support, low latency, high data rates, and economy of scale; it also raises serious security concerns. It is shown that the LTE air interface is vulnerable to denial-of-service (DoS) and loss of service attacks from power and bandwidth-limited smart jammers, without being “hacked” by them. The interaction between the network and the smart jammer is modeled as a two-player Bayesian game with asymmetric information, with the network being the uninformed player. The proposed work addresses smart jamming problem in LTE/LTE-A networks by using learning and policy optimization in repeated games so that autonomous policies can be constructed for the network to combat against these attacks.
