Automated fragment identification for electron ionisation mass spectrometry: application to atmospheric measurements of halocarbons
Myriam Guillevic, Aurore Guillevic, Martin Vollmer +4
Non-target screening consists in searching a sample for all present substances, suspected or unknown, with very little prior knowledge about the sample. This approach has been intr…
Comparing the difficulty of factorization and discrete logarithm: a 240-digit experiment
Fabrice Boudot, Pierrick Gaudry, Aurore Guillevic +3
We report on two new records: the factorization of RSA-240, a 795-bit number, and a discrete logarithm computation over a 795-bit prime field. Previous records were the factorizati…
Faster individual discrete logarithms in finite fields of composite extension degree
Aurore Guillevic
Computing discrete logarithms in finite fields is a main concern in cryptography. The best algorithms in large and medium characteristic fields (e.g., {GF}, {GF})…
Isogenies for point counting on genus two hyperelliptic curves with maximal real multiplication
Sean Ballentine, Aurore Guillevic, Elisa Lorenzo García +4
Schoof's classic algorithm allows point-counting for elliptic curves over finite fields in polynomial time. This algorithm was subsequently improved by Atkin, using factorizations…
Solving discrete logarithms on a 170-bit MNT curve by pairing reduction
Aurore Guillevic, François Morain, Emmanuel Thomé
Pairing based cryptography is in a dangerous position following the breakthroughs on discrete logarithms computations in finite fields of small characteristic. Remaining instances…
Computing Individual Discrete Logarithms Faster in GF with the NFS-DL Algorithm
Aurore Guillevic
The Number Field Sieve (NFS) algorithm is the best known method to compute discrete logarithms (DL) in finite fields , with medium to large and sm…
Improvements to the number field sieve for non-prime finite fields
Razvan Barbulescu, Pierrick Gaudry, Aurore Guillevic +1
We propose various strategies for improving the computation of discrete logarithms in non-prime fields of medium to large characteristic using the Number Field Sieve. This includes…
