HAIC Talk: 5G Security – the What, Why and How – with Alf Zugenmaier
2019-03-01 17:00 - 18:30 (Europe/Helsinki) | Dipoli, Lumituuli, Otakaari 24, Espoo, 02150, Finland
Description: Standardization of the first phase of the next generation of cellular networks has almost concluded now, and the roll out of these 5G networks is coming soon. This talk will focus on the security of 3GPP 5G network standards. It will give an understanding of how standardization works, what was standardized for security and try to shed some light to why some things are the way they are.
About the speaker: Alf Zugenmaier is professor for mobile networks and security at the university of applied sciences in Munich, Germany. He has been active in standardization within the 3GPP security standardization group since 2008, working on security standards for 4G and later 5G. Prior to becoming a professor, he worked at DOCOMO Euro-Labs in Munich, Germany, on secure mobility. Before that he was a postdoc at Microsoft Research in Cambridge, UK. He holds a PhD in Computer Science and a Diplom in Physics, both from University of Freiburg. His research interest are in network and systems security and privacy.
Venue: Lumituuli Auditorium, Dipoli, Otakaari 24, 02150 Espoo.
Time: 17:00 – 18:30 (coffee and buns served from 16:15). The lecture will be approximately 45 minutes, after which there will be time for questions.
Registration: HAIC Talks are open to everyone and free of charge but we ask you to register for the event as it helps us to estimate the number of coffees ordered, thank you.

HAIC Talks: Bitcoin, Blockchains and Smart Contracts: Understanding the Crypto in Cryptocurrencies – with Colin Boyd
2019-02-06 17:30 - 18:30
Description: Cryptocurrencies and blockchains are the most widely publicized applications of cryptography today. Using the example of Bitcoin, we will aim to understand the cryptographic building blocks of cryptocurrencies and how they fit together to enable a distributed payment system. We will then explore why newer cryptocurrencies built on Bitcoin employ more advanced cryptography. In particular we will examine the contentious issue of anonymous payments. Finally we will discuss the concept of smart contracts, how they can be achieved using blockchains, and what kinds of applications they may be useful for.
About the speaker: Colin Boyd completed a Ph.D. in Mathematics in 1995 from the University of Warwick, UK. After 5 years at British Telecom Research Laboratories, where he first became interested in cryptography and information security, he started an academic career at University of Manchester. In 1995 he emigrated to Australia and spent 18 years at Queensland University of Technology (QUT). During this time he became Research Director at the QUT Information Security Institute. In 2013 he returned to Europe, taking up a position as Professor in Information Security at the Norwegian University of Science and Technology (NTNU). His main research interests are in cryptographic protocols, including key exchange, payment systems and voting.
Venue: Lumituuli Auditorium, Dipoli, Otakaari 24, 02150 Espoo.
Time: 17:30 – 18:30 (coffee and buns served from 16:30). The lecture will be approximately 45 minutes, after which there will be time for questions.

HAIC Talk: Cybercrime in the Sky
2018-11-02 17:00 - 18:30
Description: Every day, hundreds of people fly on airline tickets that have been obtained fraudulently, and much of this is facilitated by cybercrime. I will use this example to explore cybercrime in more depth, and understand its real-world impacts. I will explore the trade in these tickets, drawing on interviews with industry and law enforcement, and an analysis of an online blackmarket. Tickets are purchased by complicit travellers or resellers from the online blackmarket. Victim travellers obtain tickets from fake travel agencies or malicious insiders. Compromised credit cards used to be the main method to purchase tickets illegitimately. However, as fraud detection systems improved, offenders displaced to other methods, including compromised loyalty point accounts, phishing, and compromised business accounts. In addition to complicit and victim travellers, fraudulently obtained tickets are used for transporting mules, and for trafficking and smuggling. I will identify the difficulties faced by law enforcement with identifying those who are complicit in this trade. I will also outline potential interventions, aimed at the act, the actor, and the marketplace, with the goal of preventing and disrupting this crime type.
About the speaker: Alice Hutchings is a University Lecturer in the Security Group at the Computer Laboratory, University of Cambridge. She is also part of the Cambridge Cybercrime Centre, an interdisciplinary initiative combining expertise from computer science, criminology, and law. Specialising in cybercrime, she bridges the gap between criminology and computer science. Generally, her research interests include understanding cybercrime offenders, cybercrime events, and the prevention and disruption of online crime.

HAIC Talk: Hard problems for cryptography: From Factoring to Sudoku - with Chris Brzuska
2018-10-09 17:45 - 19:15
Description: Cryptographers use hard problems to construct unbreakable encryption schemes, pseudorandom number generators and more. A typical example is the factoring of large numbers, i.e., we learn in primary school how to multiply numbers, but given a large number, even supercomputers struggle to take it apart into its prime factors.
In the talk, we will see the diversity of hard problems that are candidates for secure cryptography, ranging from factoring to sudoku.
About the speaker: Christopher Brzuska is a faculty member at the departments computer science and mathematics and systems analysis at Aalto University. His research area is cryptography and his activities range from investigating secure payment to generating numbers that look random although they are actually not.
Brzuska studied mathematics in Duisburg-Essen, Bordeaux and Darmstadt, holds a PhD from the computer science department at TU Darmstadt and worked as a post-doctoral researcher at Tel-Aviv University and Microsoft Research Cambridge. He was an assistant professor for IT Security Analysis at TU Hamburg where he closely collaborated with NXP Semiconductors.
