    Here are the speakers:

    • Benjamin Smith, “Fast, uniform, and compact scalar multiplication for elliptic curves and genus 2 Jacobians with applications to signature schemes” and “μKummer: efficient hyperelliptic signatures and key exchange on microcontrollers”
    • Cyril Hugounenq, “Explicit isogenies in quadratic time in any characteristic”
    • Daniel Genkin, “ECDH Key-Extraction via Low-Bandwidth Electromagnetic Attacks on PCs” and “ECDSA Key Extraction from Mobile Devices via Nonintrusive Physical Side Channels” and “CacheBleed: A Timing Attack on OpenSSL Constant Time RSA”
    • Jens Groth, “On the Size of Pairing-based Non-interactive Arguments”
    • Maike Massierer, “Computing L-series of geometrically hyperelliptic curves of genus three”
    • Mehmet Sabır Kiraz, “Pairings and Cloud Security”
    • Pascal Sasdrich, “Implementing Curve25519 for Side-Channel–Protected Elliptic Curve Cryptography”
    • Patrick Longa, “Efficient algorithms for supersingular isogeny Diffie-Hellman”
    • Razvan Barbulescu, “Extended Tower Number Field Sieve: A New Complexity for Medium Prime Case”
    • Sebastian Kochinke, “Computing discrete logarithms with special linear systems”
    • Shashank Singh, “A General Polynomial Selection Method and New Asymptotic Complexities for the Tower Number Field Sieve Algorithm”
    • Shoukat Ali, “A new algorithm for residue multiplication modulo $2^{521}-1$”
    • Tung Chou, “The Simplest Protocol for Oblivious Transfer” and “Sandy2x: new Curve25519 speed records”

    The conference organisers wish to reassure conference attendees that it is safe to come to Turkey for the conference: “The life in Izmir is just as usual: sunny and slow-going. We are preparing for ECC and we would like to serve our guests in the best way we can.”

  • The schedule for the Algorithmic Number Theory conference (ANTS) is at

  • Aurore Guillevic, François Morain and Emmanuel Thomé recently announced a solution to an ECDLP instance on a 170-bit pairing-friendly curve with embedding degree 3.
    In other words, they solved a DLP in a finite field \mathbb{F}_{p^3}^* of size around 510 bits. You can read further details here and here.

  • Thorsten Kleinjung, Claus Diem, Arjen K. Lenstra, Christine Priplata and Colin Stahlke have reported a new DLP computation using the number field sieve in a 768-bit field \mathbb{F}_{p}^*. The details are here.
