Compared to the current 4G mobile phone networks, 5G mobile networks will be faster, support more devices in the same space, connect autonomous devices such as cars and very low-power devices and will have perfect mobility with connections moving seamlessly between Wi-Fi, mobile and even satellite technologies. The networks will use Software Defined Networking (SDN) and Network Function Virtualisation (NFV), creating more flexibility but also increasing complexity.
The security of 5G networks is much more complicated than existing 3G or 4G networks: the users must be identified and authenticated in a consistent way across multiple technologies and their privacy ensured; the operators of SDNs must consider the trustworthiness of many other providers and users; added complexity brings new threats and requires additional monitoring and control.
The 5G-ENSURE project will be the reference project for everything that concerns security in 5G while contributing to 5G resilience. The project will:
The project consortium includes network operators (Orange and Telecom Italia), large equipment and service providers (Alcatel-Lucent, Ericsson, NEC and Thales) and companies, research organisations and universities working in the area of security.
IT Innovation leads the work on defining the trust model for 5G networks. The trust model defines the different people and organisations involved in using and providing 5G networks, their relationships (including liability), the threats to the elements of the network and the potential mitigations. This includes understanding the factors that affect users' propensity to trust a technical system.
IT Innovation also leads the implementation of the software to enable 5G network designers to define a network, understand the threats and see potential mitigations including an interface to integrate with run-time network monitoring systems.
This work builds on IT Innovation's work in the OPTET project where a trust model and software was developed to analyse threats in the domains of Ambient Assisted Living and Cyber Crisis Management.
This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 671562.
