IRISA cryptologists anticipate quantum attacks

Professor Pierre-Alain Fouque and CNRS researcher Adeline Langlois are anticipating the imminent arrival of quantum computers: they are developing the foundations of a cryptography capable of withstanding their extraordinary computing power.

Context

Many of the computer constructs used on the internet today will be at risk if quantum computers are built. Researchers around the world are working on several methods to resist such attacks. To guarantee data security, cryptography based on Euclidean networks is one of the most promising. At IRISA (Institut de Recherche en Informatique et Systèmes Aléatoires), the EMSEC team is particularly involved in this field.

Objective

The European project PROMETHEUS (PRivacy preserving pOst-quantuM systEms from advanced crypTograpHic mEchanisms Using latticeS) aims to propose cryptographic constructions that are resistant to quantum attacks. Its aim is to develop advanced tools by guaranteeing theoretical security based on the difficulty of algorithmic problems on Euclidean networks.

A two-step process

  • Develop signature and encryption schemes,
  • Deepen with several types of protocols preserving users' anonymity: such as anonymous authentication, electronic money or electronic voting.

Partners

The PROMETHEUS project is funded by the European Horizon 2020 programme and involves 12 European partners: ENS Lyon; ORANGE SA; CWI in Amsterdam; IBM Research; RHU London; RU Bochum; Scytl Barcelona; Thales; TNO; UPC Barcelona; WIS Rehovot; Université de Rennes 1.
