The lectures will start from 14:00 to 17:00 including 30 minutes break in between. 

The tentative schedule is as follows: 

  1. Digital signatures

   -- definitions, practical applications

   -- signatures from one-way functions

   -- random oracles and full-domain hash

   -- the Fiat-Shamir heuristic, Schnorr signatures 

  1. Lattice-based signatures: introduction

   -- post-quantum signatures

   -- early failed attempts

   -- the LWE and SIS problems

   -- tree-based signatures from lattices 

  1. Lattice-based signatures: constructions

   -- Lyubashevsky's Fiat-Shamir with aborts framework

   -- SIS vs LWE

   -- BLISS and variants

   -- overview hash-and-sign signatures 

  1. Fault attacks on lattice-based signatures

   -- the threat of physical attacks

   -- loop-abort faults on BLISS

   -- loop-abort faults on DLP

   -- possible countermeasures 

  1. Side-channel attacks on lattice-based signatures

   -- side-channels and cache timing attacks

   -- side-channel analysis of BLISS

   -- the masking countermeasure

   -- masking GLP
