International audience; Both classical and post-quantum cryptography massively use large characteristic nite elds or rings. Consequently, basic arithmetic on these elds or rings (integer or polynomial multiplication, modular reduction) may signicantl

International audience; This paper deals with Montgomery-friendly primes designed for the modular reduction algorithm of Montgomery. These numbers are scattered in the literature and their properties are partially exploited. We exhibit a large family

International audience; Pairings are a powerful tool to build advanced cryptographic schemes. The most efficient way to instantiate a pairing scheme is through Pairing-Friendly Elliptic Curves. Because a randomly picked elliptic curve will not suppor

We associate to some simplest quartic fields a family of elliptic curves that has rank at least three over ℚ(m). It is given by the equation E m : y 2 = x 3 − 36 36 m 4 + 48 m 2 + 25 36 m 4 − 48 m 2 + 25 x . $$\begin{array}{} \displaystyle E_m:

Because pairings have many applications, many hardware and software pairing implementations can be found in the literature. However, the parameters generally used have been invalidated by the recent results on the discrete logarithm problem over pair

Recent progress on NFS imposed a new estimation of the security of pairings. In this work we study the best attacks against some of the most popular pairings and propose new key sizes using an analysis which is more precise than the analysis in a rec
