Fujisaki-Okamoto — a recipe for post-quantum public key encryption
Kathrin Hövelmanns, Eindhoven University of Technology
April 3, 2024 2:00pm, in MC 5501 and Zoom
Abstract
In this talk, I will give a short introduction to Fujisaki-Okamoto, a conversion that (intuitively) turns post-quantum hardness assumptions into post-quantum secure public-key encryption. Fujisaki-Okamoto featured prominently in NIST's post-quantum standardisation effort for public-key encryption, including the emerging new standard Kyber. If time permits, I will sketch open questions surrounding Fujisaki-Okamoto and potential improvements in security and efficiency.
Bio
Kathrin is Irène Curie fellow and tenured assistant professor in the Applied and Provable Security group at Eindhoven University of Technology. Her expertise lies with provable security of cryptography when considering quantum adversaries and, more recently, the integration of quantum technologies into network security. Kathrin is especially known for her work on the provable security of post-quantum public key encryption, her work in this area is used by virtually every proposal for encryption submitted to the NIST process.
Henry Corrigan-Gibbs, MIT
TBD, in some on-campus location when things reopen
