Webinar to LORCA cohort 2: Lattice based Cryptography 101

Activity: Talk or presentation typesInvited talk


Abstract: The security of the digital world of today stands at the brink of a complete and urgent overhaul! This is due to the potential threat of realization of salable Quantum computers, since they can jeopardize the very fabric of security protocols widely deployed today. The National Institute of Standards and Technology (NIST) has started the standardization process for post-quantum cryptography (PQC), with second round announcements due this very month (February 2019). Out of various classes of post quantum cryptographic schemes submitted to the competition, the Lattice based cryptographic schemes (LBC) has emerged as one of the most promising class for standardization. There are various reasons for that: firstly, due to their efficiency and simplicity; secondly, due to their good security properties; and thirdly, due to their manifestation into more complex security functions. In view of this increasingly critical change of world wide security, this tutorial will educate and highlight some promising Lattice based cryptographic schemes schemes in the NIST competition and some initial efforts related to their implementations. We will discuss some opensource software libraries available in the context and the main bottlenecks designers face when implementing LBC on several implementation platforms.
