Dr. Ravishankar Borgaonkar works as a research scientist at Sintef Digital and undertakes research in securing next generation digital communication. His primary research themes are related to mobile telecommunication and involved security threats. This ranges from 2G/3G/4G/5G network security to end-user device security. After receiving his PhD in 'security in telecommunication' area from the technical university of Berlin, he was a security researcher at Deutsche Telekom's lab for 3 years. Since that time he has worked for Intel Collaborative Research Institute for Secure Computing at Aalto University, as well as for the University of Oxford focusing on 5G security research. He has found several protocol flaws in 3G/4G technologies and assisted in shaping the 5G security architecture. The demonstrated vulnerabilities affected billions of 3G/4G devices and resulted a change in the existing 3G/4G communication standards.
He is also a frequent speaker at the foremost computer security and industry-recognized conferences including Blackhat USA and Europe, Troopers Germany, Hack in the Box, Ruxcon Australia and many others.
Summary of the lecture
5G network promises to transform industries and our digital society by providing enhanced capacity, higher data rates, lower battery for machine-type devices, higher availability and reduced power consumptions. In a way, 5G will act as a vehicle to drive much needed digital transformation race and will push the world into the information age. In addition, 5G can be used to replace the existing emergency communication network infrastructures.
However, with a higher speed and low latency, higher bandwith availability attacks and attack surface will also be increased. In addition, in coming years, 5G may become the national critical infrastructure itself, thereby requiring new requirements, regulations, and policies to safeguard the national security interests. Several governments have been investigating different approach to build the 5G network with security and resiliency in mind.
In this talk, first we discuss how 5G is different from the current 4G/3G/2G networks from system security design perspective. Then we outline potential security challenges in deployment of 5G networks for different industries and government entities. We use previously known and severe telecom security attacks examples to demonstrate potential risks of 5G. Finally, we provide future directions to minimize security risks to build 5G enabled information transportation superhighways.
