5G security

Security is fundamental to the successful delivery of 5G networks across a wide range of industry verticals. In this research area we investigate how  5G security is different from 2G, 3G, and 4G security in relation to requirements, threat landscape and solutions.


Our work on 5G security incorporates the following topics:

  • Extending the 5G Authentication and Key  Agreement (AKA): to provide anchor of trust for applications such as Internet of Things (IoT) and Intelligent Transport Systems
  • Identify threats and solutions to 5G technologies such as Software Defined Networks (SDN) and Network Function Virtualisation (NFV)
  • Security management for 5G Emergency communications (Mission Critical Communications) including security integration of 5G and satellite networks
  • User and data Privacy protections and using identity hiding techniques such as Pseudonyms and Pseudonym management and Distributed Ledger Technology for large scale systems
  • Light weight authentication and distributed trust management for Intelligent Transport Systems using statistical methods and Artificial Intelligence (AI).
