DESCRIPTION:TITLE:Compact Lattice Signatures via Iterative Rejection Sampli
 ng\n(ePrint: 2024/2052 [https://eprint.iacr.org/2024/2052.pdf])\n\nSpeaker
 \n Seunghoon Lee\n\nAffiliation\n University of Waterloo\n\nLocation\n MC 
 5479\n\nABSTRACT: This talk reviews the paper by Joel Gärtner that recei
 ved\none of the Best Paper Awards at CRYPTO 2025. The work introduces a ne
 w\nmethod for constructing lattice signatures using the “Fiat–Shamir\n
 with aborts” approach. By carefully designing the rejection\ncondition\,
  the authors significantly lower the rejection probability.\nThis leads to
  a signature scheme that is much more compact than\nprevious lattice-based
  Fiat–Shamir signature schemes. In this talk\,\nwe will carefully examin
 e the proposed techniques as well as the\nconcrete parameters that enable 
 such compact signatures.
