    The Fiat-Shamir with Aborts paradigm (FSwA) uses rejection sampling to remove a secret’s dependency on a given source distribution.  Recent results revealed that unlike the uniform distribution in the hypercube, both the continuous Gaussian and the uniform distribution within the hypersphere minimise the rejection rate and the size of the proof of knowledge. However, in practice both these[…]

Presentation of the seminar

  • Scientists welcome the renewed interest and original insight that cryptography brings to their disciplines, as well as the intellectual challenges posed to them.

    Multidisciplinary par excellence, cryptography constitutes a point of contact between number theory, algebraic geometry, algorithms and computer science. It brings whole sections of the most fundamental mathematics into contact with applications of great practical importance.

    Board :

    • The General Directorate of Armament (DGA) : state body responsible for the development of cryptographic algorithms, which depends on the the Ministry of the Armed Forces.
    • Rennes Mathematical Research Institute (IRMAR) : mathematics research laboratory associating the National Center for Scientific Research (CNRS), the University of Rennes, the École Normale Supérieure de Cachan (ENS Cachan), the National Institute of Applied Sciences of Rennes (INSA Rennes) and the University of Rennes 2.
    • Institute for Research in Computer Science and Random Systems (IRISA): computer science research laboratory in Rennes.

    DGA, IRISA and IRMAR wish, by organizing this cooperative seminar, to crystallize the interest of different actors in the Rennes region around cryptography and, beyond current fashion, to encourage fruitful and scientific collaboration. quality.
