SUMMARY:Kernelization\, Proof Complexity and Social Choice
DESCRIPTION:Title: Kernelization\, Proof Complexity and Social Choice \nSpeaker: Gabriel Istrate (West University of Timișoara) \n\nAbstract:  \n\nWe display an application of the notions of kernelization and data reduction from parameterized complexity to proof complexity: Specifically\, we show that the existence of data reduction rules for a parameterized problem having (a) a small-length reduction chain\, and (b) small-size (extended) Frege proofs certifying the soundness of reduction steps implies the existence of subexponential size (extended) Frege proofs for propositional formalizations of the given problem. We apply our result to infer the existence of subexponential Frege and extended Frege proofs for a variety of problems. Improving earlier results of Aisenberg et al. (ICALP 2015)\, we show that propositional formulas expressing (a stronger form of) the Kneser-Lovasz Theorem have polynomial size Frege proofs for each constant value of the parameter k. Previously only quasipolynomial bounds were known (and only for the ordinary Kneser-Lovasz Theorem). Another notable application of our framework is to impossibility results in computational social choice: we show that\, for any fixed number of agents\, propositional translations of the Arrow and Gibbard-Satterthwaite impossibility theorems have subexponential size Frege proofs. \nThis is joint work with Cosmin Bonchiș and Adrian Crăciun.

SUMMARY:Cybersecurity of Industrial Control Systems
DESCRIPTION:Title: Cybersecurity of Industrial Control Systems \nSpeaker: Stéphane Mocanu (INRIA) \n\nAbstract: In this talk\, we discuss the state of the art of industrial control systems cybersecurity. Based on classical events\, we analyse the typical threats and the vulnerabilities that they exploit. In the second part of the talk\, we present the security architectures and security practices as recommended by international standards (ISO 27000\, IEC 62443) and NIST Cybersecurity Framework).
