The Institute for Logic, Language and Computation (ILLC) is looking for is looking for a PhD candidate in the area of post-quantum cryptography.

The aim of the PhD project is to carry out quantum cryptanalysis of the most promising schemes in the NIST competition for post-quantum cryptography. The objective ranges from identifying potential vulnerabilities in the design to possibly discovering complete breaks, but also considers the question of finding the right choice of parameters for schemes that (seem to) withstand quantum attacks.

Supervision will be shared between QuSoft and Mathematisch Instituut (MI) Leiden, with Christian Schaffner (University of Amsterdam / QuSoft) and Peter Stevenhagen (MI Leiden) as main supervisors and Serge Fehr (CWI/QuSoft) and Peter Bruin (MI Leiden) as co-supervisors. Additionally, collaboration with Leo Ducas (CWI) and Stacey Jeffery (CWI/QuSoft) and Marco Streng (MI Leiden) is anticipated.

You will be expected to contribute to the QuSoft research agenda. Specifically, you will be asked to perform the following tasks: 

  • complete and defend a PhD thesis within the official appointment duration of four years;

  • regularly present intermediate research results at international workshops and conferences and publish them in proceedings and journals;

  • participate in the organisation of research activities and events at ILLC and QuSoft, such as conferences, workshops and joint publications;

  • contribute to the UvA’s educational programme by working as a teaching assistant for a course in the area of your expertise and/or by assisting with the supervision of student research projects. ​


You should hold a Master's degree (or expect to obtain this by the end of the academic year 2017/18) with excellent grades in computer science, mathematics or physics with outstanding results or a comparable degree.

Furthermore you should also possess:

  • preferably, a strong background in cryptography, quantum algorithms and/or mathematics (relevant to post-quantum cryptography);
  • demonstrated research abilities, e.g. by completion of an (undergraduate) research project;
  • good academic writing and presentation skills;
  • good social and organisational skills;
  • full professional proficiency in spoken and written English.


You will be employed by the Faculty of Science at the University of Amsterdam on a fixed-term full-time position (38 hours per week).

Your appointment is intended to be for a period of four years. The initial contract will be for 18 months. This will be extended with a further 30 months after a positive evaluation. we will draw up an educational plan that includes attendance of courses and (international) meetings.

Your gross monthly salary amounts to €2,222 during the first year, rising to €2,840 during the fourth year, and will be supplemented with an 8% holiday allowance and an 8.3% end-of-year bonus. The Collective Labour Agreement for Dutch Universities applies.

Preferred starting date 1 September 2018.
