Deniable Secret Sharing

Series: Department Seminar

Speaker: Sophia Yakoubov, Assistant Professor, Aarhus University

Date/Time: Mar 13 09:30:00

Location: CSA Auditorium, (Room No. 104, Ground Floor)

Abstract:
We introduce deniable secret sharing (DSS), which, analogously to deniable encryption, enables shareholders to produce fake shares that are consistent with a target �??fake message�?�, regardless of the original secret. In contrast to deniable encryption, in a DSS scheme an adversary sees multiple shares, some of which might be real, and some fake. This makes DSS a more difficult task, especially in situations where the fake shares need to be generated by individual shareholders, without coordination with other shareholders.
