LOCATION: Kristen Nygaards sal (room 5370), Ole Johan Dahl's House.
14:00h Welcome at IFI
14:15h Talk: Post-Quantum Cryptography: A Concise Overview
Presentation slides: Post-Quantum Cryptography
SPEAKER: Thomas Gregersen, NSM
ABSTRACT: Cryptographic research is constantly on the move as new cryptanalytical techniques become available. After the discovery of quantum algorithms that can overcome the computational complexity of cryptographic primitives in current mainstream algorithms, the search is on to find suitable candidate primitives for new quantum-resistant algorithms. This research field carries the banner of post-quantum cryptography.
I will try to give an overview of how quantum algorithms come into play in cryptanalysis and which problems arise for current cryptography. Finally I will sketch some of the families of primitives that have been proposed in the quest for finding solutions that may survive in the post-quantum era.
SPEAKER BIO: Thomas Gregersen holds a PhD in mathematics from the University of Oslo. In 2014 he joined NSM (National Security Authorithy) as a researcher.
