DESCRIPTION:Ngoc Khanh Nguyen\, postdoctoral researcher at EPFL - COMPSEC 
 Lab\nThe EDIC program is happy to invite you to a public talk by our post 
 doctoral researcher Ngoc Khanh Nguyen who is working in the COMPSEC Lab wi
 th prof. Alessandro Chiesa.\nThe aim of the talk is to present his achieve
 ments to a broad audience to prepare for hiring interviews coming up soon.
  Be sure to join\, listen to the talk and participate in the Q&A session a
 t the end of the presentation.\n\nAbstract\nIn preparation for the eventua
 l arrival of quantum computers\, there has been a significant amount of wo
 rk to construct quantum-safe cryptographic primitives\, as evidenced by th
 e ongoing NIST PQC Standardization. To ensure post-quantum security\, the 
 underlying public-key schemes have to be built based on quantum-safe compu
 tational hardness assumptions.  \nIn this regard\, lattice-based primitiv
 es appear to be a leading choice. Indeed\, the currently most efficient\, 
 in terms of size and speed\, quantum-safe basic primitives (e.g. signature
 s and encryption schemes) are based on the hardness of lattice problems wi
 th algebraic structure. As a natural next step\, lattice-based cryptograph
 y can be thus applied to build more advanced primitives such as zero-knowl
 edge proofs.\nI will start by describing our lattice-based linear-sized ze
 ro-knowledge framework (Crypto 2022)\, which can be useful for building ef
 ficient privacy-oriented applications\, such as confidential payment syste
 ms or anonymous credentials. In the second part of the talk\, I will give 
 an overview of the current constructions and open problems related to subl
 inear-sized proof systems from lattices.\n\nBio\nNgoc Khanh Nguyen is post
 doctoral researcher at EPFL\, hosted by Prof. Alessandro Chiesa. His curre
 nt topics of interests are (but not limited to) efficient lattice-based co
 nstructions and efficient post-quantum zero-knowledge proofs. Previously\,
  he obtained his PhD degree at ETH Zurich and IBM Research Europe - Zurich
 \, supervised by Dr Vadim Lyubashevsky and Prof. Dennis Hofheinz.  \nBefo
 re that\, he did his undergraduate and master studies at the University of
  Bristol\, UK.
