摘要:Recent advances in the Internet of Things and quantum computers, has raised fundamental challenges to the long-term security of information in today’s cyber-physical world.  In many cases, information needs long- term protection. Examples are national security data, trade secrets, and personal health data. However extreme connectivity means that data must be protected end-to-end and at all layers of networks, and the prospect of development in quantum computing demands algorithms and protocols to stay secure when quantum computers exist.

Building security on physical layer assumptions provides an attractive alternative for secure end-to-end communication. In this talk we will look at a number of physical layer assumptions that aim to capture adversaries’ power in communication systems, give cryptographic security definitions for systems that use these assumptions, and outline constructions with provable security. We discuss challenges of implementing these systems.

个人介绍:Rei Safavi-Naini is the AITF Strategic Chair in Information Security and a founding Director of Institute for Security, Privacy and Information Assurance at the University of Calgary. Before joining the University of Calgary in 2007 as the iCORE Chair in Information Security, she was a Professor of Computer Science and the Director of Telecommunication and Information Technology Research Institute (now ICT Research Institute) at the University of Wollongong Australia.

She has over 300 refereed publications, has served as an Associate Editor of IEEE Transactions on Information Theory, ACM Transactions on Information and System Security (TISSEC), and is currently an Associate Editor of IEEE Transactions on Secure and Dependable Computing, IET Information Security and Journal of Mathematical Cryptology. She has served as Program Chair/co-Chair of numerous conferences, most recently, ACM CCSW 2014, Financial Cryptography 2014, ACNS 2013 and Crypto 2012. She is a member of the Steering Committee of International Conference in Information Theoretic Security and ACM CCS Cloud Computing Security Workshop.

She has a PhD in Electrical Engineering from University of Waterloo, Canada.

Her current research interests are cryptography, information theoretic security, quantum-safe cryptography, network and communication security and privacy, and Cloud security and privacy.
