The HAIC public outreach initiative aims to make information security more accessible to a broader audience. As part of this initiative, they are organizing HAIC Talks, a series of public lectures on contemporary topics in information security. In the style of studia generalia, these lectures are free and open to everyone. No background knowledge in information security is required. HAIC Talks are made possible through the generous support of the Aalto University School of Science.

Venue: Lumituuli Auditorium, Dipoli, Otakaari 24, 02150, Espoo.

Time: 18:00 – 19:30 (doors open at 17:30). The lecture will be approximately 60 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.

The Advertisement Exchange: How to Develop Agile Cryptographic Support for an Evolving Ecosystem?

Abstract:

Developing of Systems within a global infrastructure (or a cloud) has to take into account that the underlying system will evolve, new versions of software will develop, and if the system is successful then further services will be added. The development of security tools to such systems has to consider agility and scale-up of the initial design and adaptation to the evolving nature of the system. In fact, we argue that this is a basic principle in deployment of security solutions in modern global ecosystems. For example, cryptographic solutions have to be designed with extended scope in mind and with enough flexibility to allow the growing system to be able to exploit the existing cryptographic tools and methods (since a drastic change may be overly complex and will result in much development overhead).We demonstrate this “agility principle” by reviewing the development of cryptographic solution to Google’s global Advertisement Exchange (ADX), which is the system managing auctions for placing banner ads throughout the Internet.

Moti Yung is a Security and Privacy Scientist with a main interest in Cryptography: its Theory and its Real life Applications. He graduated from Columbia University in 1988 and is an adjunct senior research faculty at Columbia till today. In parallel he has had an industrial research career working at places like IBM, RSA Labs. (EMC), Google, and Snap. Yung is a fellow of ACM, of IEEE, of the International Association for Cryptologic Research (IACR) and the European Association for Theoretical Computer Science (EATCS). Among his awards are ACM’s SIGSAC Outstanding Innovation Award in 2014, and 2018 IEEE Computer Society W. Wallace McDowell Award. His research covers broad areas: from the theory and foundations, to applied systems, and actual engineering efforts of cryptography and secure systems.
