SUMMARY:Deniable encryption in a quantum world - Andrea Coladangelo (Unive
 rsity of Washington)
DTSTART:20241203T140000Z

CONTACT:Tom Gur
DESCRIPTION:The topic of this talk fits into the broad direction of levera
 ging quantum information to realize cryptographic functionalities that are
  impossible to realize classically. I will describe an example of how quan
 tum information can provide a form of protection against coercion (for exa
 mple\, in online elections) that is unattainable classically. More concret
 ely\, I will introduce a quantum extension of the notion of “deniable en
 cryption”\, which is well studied classically\, and I will describe a co
 nstruction satisfying the new notion based on the hardness of the learning
  with errors problem (LWE). \n\nThis is based on joint work with Shafi Gol
 dwasser and Umesh Vazirani.
