SUMMARY:Tutte Colloquium - Tibor Jager
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Tightly-Secure Digital Signatures\n\nSpeake
 r:\n Tibor Jager\n\nAffiliation:\n University of Wuppertal\, Germany\n\nZo
 om:\n Please email Emma Watson\n\nABSTRACT:\n\nThis talk will cover two r
 ecent results on tightly-secure digital\nsignature schemes from PKC 2021 a
 nd ASIACRYPT 2021.\n\nThe first part will consider a strong multi-user sec
 urity definition\nfor signatures with adaptive corruptions of secret keys\
 , discuss its\napplications\, and the technical challenges of constructing
  signatures\nwith tight security in this setting. Then we will show a quit
 e simple\nand efficient construction\, based on sequential OR-proofs.\n
