HAIC Talk: Hard problems for cryptography: From Factoring to Sudoku – with Chris Brzuska
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…

HAIC Talk: Cybercrime in the Sky
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…

HAIC Talks: Bitcoin, Blockchains and Smart Contracts: Understanding the Crypto in Cryptocurrencies – with Colin Boyd
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,…

HAIC Talk: 5G Security – the What, Why and How – with Alf Zugenmaier
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…
