Trusted Execution Environment-Enabled Platform for 5G Security and Privacy Enhancement
Published in Studies in Big Data, 2021
With the deployment of 5G networks and the beginning of the design of beyond 5G communications, new critical requirements are emerging in terms of performance, security, and trust for leveraged technologies, such as Software Defined Networking (SDN) and Network Function Virtualization (NFV). One of the requirements at the security and trust level is that when delegating critical tasks and data to the infrastructure deployed in an external domain, the client needs guarantees that the execution has been carried out securely, without data breaches or compromises during computing tasks. To meet this need, this chapter proposes a framework that uses Trusted Execution Environments (TEEs), processing environments isolated from the rest of the system to guarantee the security of the data and tasks processed in them, in order to improve the security of 5G environments. This framework enables the deployment of TEE as a cloud service, also denoted as TEE-as-a-Service or TEEaaS, allowing customers to take advantage of its benefits without having to deal with the configuration of the environment and hardware. Furthermore, this chapter also discusses current trends as well as future challenges related to the deployment of TEEs in 5G environments, providing key aspects for future solutions in the area.
