Security and Trust in Current and Future Wireless Networks


Prof. John S. Baras
University of Maryland, College Park, MD, USA



Abstract: We consider security and trust problems in the rapidly evolving and changing area of wireless networks. Several technologies including 5G, IoT, Software Defined Networks (SDN) and Network Function Virtualization (NFV) are rapidly changing the landscape. They lead at the same time to new challenges and to new opportunities for providing better security and trust. We describe some of these challenges and their implications for a diverse set of applications ranging from communication and sensor networks to networked cyber-physical systems. We next focus on trust schemes and their analysis in these current and future networks. We describe our results on various distributed consensus problems and the significance of trust schemes on the convergence and performance of such prototypical distributed inference and decision making algorithms. These include analysis using formal models, game theory and multi-metric hybrid optimization. We next describe the new opportunities provided by SDN, NFV, and network slicing, especially in the context of dynamic, adaptive on-demand network provisioning. We consider trust-based and trustless-based (i.e. blockchain) options, and the fundamental tradeoffs arising. We discuss applications to social networks, sensor networks, distributed control of CPS, autonomous vehicles. We close by describing future challenges and research directions.

Status of 5G security


Prof. Valtteri Niemi
University of Helsinki, Finland



Abstract: Based on several years of research and study in 5G security the 3GPP started to write the first standard specification one year ago. Now the security specification for the first phase of 5G is almost finalized and it is a good time to look at what has been achieved. The first observation is that 5G security can be seen as an extended version of 4G security, which in turn is an extended version of 3G security. Many things have been changed but this is mainly because of non-security reasons. Cellular security features are embedded into radio and mobility management procedures, hence changes in these procedures require adaptations for security also. The second observation is that there are also purely security-motivated enhancements. Two examples are user identity protection against active attackers (IMSI catchers) and improved home operator control of security in roaming situations. The third observation is that many of the highly promoted properties of 5G, e.g. low latency and support for massive number of IoT devices, have been postponed to phase 2 in 3GPP. This means that the specification work for these properties is just starting. Introduction of 5G phase 2 features has many consequences in security and privacy. It is therefore expected that phase 2 security specification work will face many interesting challenges.

Biography: Valtteri Niemi is a Professor of Computer Science in University of Helsinki and leads the Secure Systems research group. Earlier he has been a Professor of Mathematics in two other Finnish universities: University of Vaasa during 1993-97 and University of Turku during 2012-2015. Between these two academic positions Niemi served for 15 years in various roles at Nokia Research Center and was nominated as a Nokia Fellow in 2009. At Nokia, Dr. Niemi worked for wireless security, including cryptological aspects and privacy-enhancing technologies. He participated 3GPP SA3 (security) standardization group from its beginning and during 2003-2009 he was the chairman of the group. He has published more than 80 scientific articles and he is a co-author of four books and more than 30 patent families.



Things, Threats, Trust: Tackling Security & Privacy Challenges in the Brave New IoT World


Prof. Ahmad-Reza Sadeghi
TU Darmstadt, Germany



Abstract: IoT devices are widely being adopted as new manufacturers of internet-connected devices are entering the market. Although IoT promises a brave new world, many devices are lacking proper security designs or have flawed implementations, making them vulnerable to various security and privacy threats. We are facing significant challenges specific to IoT, such as emerging large-scale IoT botnet attacks, abuse of voice-based virtual assistants (e.g., Amazon’s Alexa), or novel privacy threats caused by widespread adoption of wireless sensors, actuators and smart home appliances even in presence of properly encrypted communications.
Unfortunately, existing intrusion detection techniques for detecting compromised IoT devices seem ineffective given the massive scale of the IoT device population and enormous diversity of device hardware, operating systems, software frameworks and manufacturers involved.
In this talk, we will present our recent work on addressing various security and privacy challenges in the growing IoT landscape including industry collaborations. In particular, we focus on approaches for identifying IoT devices based on their inherent communication behavior and using these behavior patterns to automatically detect compromised IoT devices effectively.

Biography: Ahmad-Reza Sadeghi is a professor of Computer Science at TU Darmstadt, Germany where he heads the System Security Lab at the Cybersecurity and Privacy Research Center (CYSEC). Since 2012 he is the director of the Intel Collaborative Research Institute for Collaborative Autonomous & Resilient Systems (ICRI-CARS). For his influential research on Trusted Computing he received the renowned German “Karl Heinz Beckurts” award. This award honors excellent scientific achievements with high impact on industrial innovations in Germany. He is the author of more than 300 peer-reviewed scientific publications in the field of IT security and privacy and was, amongst others, Editor-In-Chief of the prestigious IEEE Security and Privacy Magazine. He is also on the advisory board of several large multinational IT-enterprises.
