Updating key size estimations for pairings

Authors: Razvan Barbulescu, Sylvain Duquesne


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 recent article of Menezes, Sarkar and Singh. We also select pairing-friendly curves for standard security levels.
