Post-quantum security of symmetric-key constructions

Speaker
Chen Bai(QuICS)
Event Type
QCCC Seminar
Date & Time
December 7, 2022, 1:00pm
Where to Attend
ATL 3100A and Virtual Via Zoom
In this talk I will give a brief introduction about the security of various symmetric-key constructions against quantum attackers in two models: Q1 model and Q2 model. I’ll talk about the difference between those two models, why Q1 model is more realistic and some recent results about the post-quantum security of block ciphers in the Q1 model.
