On the Physical Security of Multivariate Signature Schemes

Talk by Prof. Dr. Juliane Krämer

Speaker invited by: Prof. Dr. Joachim Rosenthal

Date: 26.11.25  Time: 15.15 - 16.15  Room: Y27H28

Multivariate signature schemes are interesting for use cases where post-quantum security and short signatures are required. Currently, the most relevant multivariate signature schemes are UOV - which is already 25 years old -, and variants of the UOV scheme. In this talk, I will present recent insights on the physical security of UOV-based signature schemes, i.e., their security with respect to side channel and fault attacks.
