Logarithme discretLe logarithme discret est un objet mathématique utilisé en cryptologie. C'est l'analogue du logarithme réel qui est la réciproque de l'exponentielle, mais dans un groupe cyclique G fini. Le logarithme discret est utilisé pour la cryptographie à clé publique, typiquement dans l'échange de clés Diffie-Hellman et le chiffrement El Gamal.
Moduli stack of elliptic curvesIn mathematics, the moduli stack of elliptic curves, denoted as or , is an algebraic stack over classifying elliptic curves. Note that it is a special case of the moduli stack of algebraic curves . In particular its points with values in some field correspond to elliptic curves over the field, and more generally morphisms from a scheme to it correspond to elliptic curves over . The construction of this space spans over a century because of the various generalizations of elliptic curves as the field has developed.
Elliptic curve primalityIn mathematics, elliptic curve primality testing techniques, or elliptic curve primality proving (ECPP), are among the quickest and most widely used methods in primality proving. It is an idea put forward by Shafi Goldwasser and Joe Kilian in 1986 and turned into an algorithm by A. O. L. Atkin the same year. The algorithm was altered and improved by several collaborators subsequently, and notably by Atkin and de, in 1993. The concept of using elliptic curves in factorization had been developed by H. W.
