Nouveaux records de factorisation et de calcul de logarithme discret

Abstract : This article describes two new records established at the end of 2019 : an integer factorization record for thefactorization of RSA-240, and a discrete logarithm record of the same size. These two records correspond to 795-bit numbers, or 240 decimal digits, and were established with the same open-source CADO-NFS software, onthe same type of processors. These records serve as a reference for key size recommendations for cryptographic protocols.
