Description
In the past few years, the interest for rank metric based cryptography has drastically increased, especially since the beginning of the NIST Post-Quantum Cryptography standardization process : five rank metric based proposals were submitted to the first round. This talk will present the different approaches and tradeoffs for building Key Encapsulation Mechanisms and Public Key Encryption schemes based on the rank metric, as well as the recent works on digital signature schemes.<br/> lien: http://desktop.visio.renater.fr/scopia?ID=725941***7609&autojoin

Key Attack on the ACDGV Matrix Encryption Scheme
Speaker : Anmoal Porwal - Technical University of Munich
I will present our key-recovery attack on the ACDGV public-key encryption scheme proposed at ASIACRYPT 2024 by Aragon, Couvreur, Dyseryn, Gaborit, and Vinçotte. The secret key is a Gabidulin code hidden by appending random rows and columns and by left- and right-multiplication with invertible matrices. Our attack exploits the resulting algebraic structure to recover an equivalent secret key. It[…]-
