Title: Rotational Differential-Linear Cryptanalysis of ARX Ciphers

Speaker: Siwei Sun Affiliation: University of Chinese Academy of Sciences Zoom: Please email Jesse Elliott

Abstract:

The differential-linear attack, combining the power of the two most effective techniques for symmetric-key cryptanalysis, was proposed by Langford and Hellman at CRYPTO 1994. We further extend this framework by replacing the differential part of the attack by rotational differentials.

Title:  A curious identity between the orthogonal Brezin--Gross--Witten integral and Schur symmetric functions via b-deformed monotone Hurwitz numbers

Speaker: Maciej Dolega Affiliation: IMPAN Zoom: Please email Olya Mandelshtam

Abstract:

This talk is intended for an algebraic combinatorial community and no prior knowledge is required. All the difficult words (Hurwitz numbers, KP hierarchy, HCIZ and BGW integrals, Jack symmetric functions, the b-conjecture) will be explained and gently introduced.
