New:  Lattice Encryption and Signatures Tutorial


Vadim LyubashevskyI am a cryptographer in the Security group at IBM Research - Zurich , where I have worked since 2015.  From 2010-2015, I was an Inria researcher (chargé de recherche) in the crypto group at the École Normale Supérieure in Paris, and prior to that, a post-doc in the Foundations of Computing group at Tel-Aviv University (hosted by Oded Regev) from 2008 - 2010.   I received my Ph.D. from the University of California, San Diego (advised by Daniele Micciancio) in 2008. 

My main research focus is on designing efficient cryptographic protocols based on the hardness of lattice problems.  Part of this research is supported by an ERC starting research grant FELICITY (Foundations of Efficient Lattice Cryptography), the goal of which is to design practical public key cryptographic schemes that will remain secure even in the presence of quantum computers.


The Ph.D. students with whom I currently have the pleasure of working with are:

  • Ngoc Khanh Nguyen (Ph.D. student) Sept. 2018 - 
  • Gregor Seiler (Ph.D. student) Jan. 2017 -


My previous students and post-docs (at IBM and ENS) were:

  • Jonathan Bootle (Postdoc)
  • Rafael del Pino (Ph.D. student)
  • Pierrick Meaux (Ph.D. student)
  • Thijs Laarhoven (Postdoc)
  • Thomas Prest (Ph.D. Student)
