Breakthrough research using quantum cryptography addresses security in 5G networks
7 March 2019
New research has demonstrated a ground-breaking solution for securing future critical communications infrastructures, including emerging 5G networks.
The research addresses widely reported concerns on security vulnerability of 5G networks which are predicted to transform the telecommunications industry in the next ten years. The work was carried out by the High Performance Networks (HPN) Research Group at the University of Bristol's Smart Internet Lab and following a competitive peer review selection process.
The findings are presented today (7 March) at a highly prestigious post-deadline paper in the Optical Fibre Communication Conference (OFC), San Diego, USA.
The proposed solution will enable 5G network operators to offer ultimately secure 5G services while guaranteeing ultra-low-latency and high-bandwidth communications. This is due to the novel combination of quantum and infrastructure virtualization technologies.
