Adrian Perrig


Adrian Perrig is a Professor at the Department of Computer Science at ETH Zürich, Switzerland, where he leads the network security group. He is also a Distinguished Fellow at CyLab, and an Adjunct Professor of Electrical and Computer Engineering at Carnegie Mellon University. 



Imagining a new Internet architecture enables us to explore new networking concepts without the constraints imposed by the current infrastructure. What are the benefits of a routing protocol that does not rely on global convergence? What about a data plane without inter-domain forwarding tables on routers? What secure systems can we build if a router can derive a symmetric key for any host within 20ns?

In this presentation, we invite you to join us on our 11-year long expedition of creating a next-generation secure Internet architecture: SCION. SCION has already been deployed at several ISPs and domains, and has been in production use for the past 3 years. On our journey, we have found that path-aware networking and multipath communication not only provide security benefits, but also enable higher efficiency for communication, increased network capacity, and even reduce power utilization.

Harri Holma

Fellow, Nokia Bell Labs

Harri Holma joined Nokia Research Center in 1994 and received his M.Sc. from Helsinki University of Technology 1995. He has been with Nokia since 1994 and has been located both in Finland and in USA during that time. Harri Holma is currently working as Fellow in Nokia Bell Labs with special interest on radio system performance. He has completed his PhD at Helsinki University of Technology 2003. Dr. Holma has edited the books "WCDMA for UMTS", "HSDPA/HSUPA for UMTS", "LTE for UMTS", “Voice over LTE”, “LTE Advanced”, “HSPA+ Evolution”, “LTE Small Cell Optimization” and “5G Technology”, and contributed to a number of other books in the radio communication area.

Radio network evolution with 5G and beyond

5G deployment started commercially during 2019 by providing high performance mobile broadband services in the excess of 1 Gbps with Non-Standalone (NSA) architecture on mid-band TDD frequencies. 5G rollouts expanded to other bands including wide area FDD bands and millimeter wave frequencies. Commercial Standalone (SA) architecture with 5G core network was kicked off commercially during 2020. Impressive performance but we have only seen the very early phase of 5G technology so far. The next phase in 5G brings many advanced capabilities including Ultra Reliable Low Latency Communication (URLLC), Industrial IoT optimization, new frequency bands, enhancements for multiantenna operation, support for new verticals like public safety, car-to-car and satellite communication. The radio evolution continues even further beyond short term 5G improvements towards 6G. This key note will illustrate the attractive capabilities that the radio technology innovations can bring for the mobile industry.

Resource allocation is important in wireless communications to distribute resources efficiently among users, but not widely used for security purpose. Cellular underlay vehicle-to-vehicle (V2V) communications play an important role in next generation mobile communications, where security is a critical issue.

Most previous works relied on time-consuming encryption / authentication algorithms to ensure V2V communication security. This talk focuses on implementation of PHY-layer security via resource allocation. We formulate a secrecy capacity optimization problem, which is solved via decomposing a joint optimization problem into two subproblems: optimal subcarriers and power allocation problems. The subcarriers allocation subproblem is a three-dimensional (3D) search problem. We develop an iterative algorithm, based on which we transform a non-convex power allocation problem to a convex form before solving it using an alternating maximization (AM) algorithm.

Simulation results validate the performance of the proposed resource allocation based PHY-layer security scheme.
