This major is run by the Mathematics Research and Training Unit (UFR) at Université de Rennes 1.

Students enrolled for this major are graduates of a Master’s in Mathematics and Applications – IT Mathematics and Cryptography.




This major trains specialist mathematical engineers to become digital information protection experts. The programme is geared towards students who have graduated with a Mathematics degree and students who wish to develop the necessary skills to deal with rapidly changing information sectors (cryptography, error correction) in which mathematics play an ever-increasing role.

Because cryptography has had a strong foothold in Rennes since the 80s, this Master’s programme is taught within a framework at the forefront of cryptography. The programme’s teaching staff come from academic, research (IRMAR and IRISA labs) and industrial sectors (DGA-MI – Information Control Defence Agency, Orange Labs, and Amossys, amongst others).

Training programme objectives

Students will gain in-depth understanding of cryptography by learning the necessary theory behind modern cryptography and information theory, as well as practical knowledge for effective application in real life.

Fundamental mathematics for modelisation and digital information processing include several branches of mathematics, such as algebra, geometry, combinatorics and probability.

The aim of this Master’s is to teach students how to handle complex mathematics both from a theoretical and algorithmic point of view.

Acquired skills

  • Expertise in symmetric, asymmetric, post-quantum, cryptanalysis and, hidden channel attack, cryptography
  • Proficiency in complex mathematics for use in a range of areas (mobile telephones, wireless networks, remote internet transactions, widespread use of smart cards in securing commercial transactions, biometric identification techniques, remote identification)
  • Dual skills in mathematics and IT to enable students to work in information security, IT security and security software development
  • Ability to adapt to new problems, attacks and environments


A comprehensive, interdisciplinary programme which focuses on digital security issues and includes mathematics, digital technologies and sciences, and human and social sciences.

Employment opportunities

Increasing digital activity means that cryptography is a rapidly-developing sector. The Master’s programme delivers dual proficiency in mathematics and IT, which is rare in the current job market. Graduates are able to apply for the following positions:

  •  R&D Engineer and IT Security Developer
  •  Research Engineer specialised in IT security
  •  Security Software Developer

CyberSchool also has solid research links enable students to continue their studies to PhD level.


This Master’s is part of a partnership between the Rennes Institute of Mathematical Research (IRMAR) and the French Directorate General of Armaments’ cryptography lab (DGA) in charge of creating government cryptography algorithms. The DGA is a stakeholder in the EUR Cyberschool.

IRISA (Research Institute of Computer Science and Random Systems) cryptography research teams also work closely with the Master’s programme.

The programme has been granted the ANSSI (French national agency for information systems security) SecNumedu label.
