SUMMARY:Tutte Colloquium - Tibor Jager
CLASS:PUBLIC
DESCRIPTION:TITLE: Tightly-Secure Digital Signatures\n\nSpeaker:\n Tibor J
 ager\n\nAffiliation:\n University of Wuppertal\, Germany\n\nZoom:\n Please
  email Emma Watson\n\nABSTRACT:\n\nThis talk will cover two recent result
 s on tightly-secure digital\nsignature schemes from PKC 2021 and ASIACRYPT
  2021.\n\nThe first part will consider a strong multi-user security defini
 tion\nfor signatures with adaptive corruptions of secret keys\, discuss it
 s\napplications\, and the technical challenges of constructing signatures\
 nwith tight security in this setting. Then we will show a quite simple\nan
 d efficient construction\, based on sequential OR-proofs.
