Accepted papers to Eurocrypt, PQ Crypto and PKC 2019

The Eurocrypt 2019 program features a lot of interesting papers. There are two papers relevant to isogeny crypto:

  • Daniel J. Bernstein, Tanja Lange, Chloe Martindale and Lorenz Panny. Quantum Circuits for the CSIDH: Optimizing Quantum Evaluation of Isogenies.
  • Luca De Feo and Steven Galbraith. SeaSign: Compact Isogeny Signatures from Class Group Actions.

The PQ Crypto 2019 program features three papers on isogeny crypto:

  • Thomas Decru, Lorenz Panny and Frederik Vercauteren. Faster SeaSign signatures through improved rejection sampling.
  • E.V. Flynn and Yan Bo Ti. Genus Two Isogeny Cryptography.
  • Michael Meyer, Fabio Campos and Steffen Reith. On Lions and Elligators: An efficient constant-time implementation of CSIDH.

The PKC 2019 program includes the paper:

  • Steven D. Galbraith, Jake Massimo and Kenneth G. Paterson. Safety in Numbers: On the Need for Robust Diffie-Hellman Parameter Validation.

    This paper shows how to construct elliptic curves whose group order is a composite that passes some primality tests with moderate probability. The paper explains why this has implications in some Diffie-Hellman settings.
