An Efficient Privacy-Preserving E-coupon Systemnonymity/unlinkability. However, achieving both traceability against dishonest users and anonymity for honest users without involving any third party is an open problem that has not been solved by the previous work. Another desirable feature of an e-coupon system that has not been studied in the lit

Private Aggregation with Custom Collusion Toleranceheless, many applications need this functionality, while others need it for simpler computations; operations such as multiplication or addition might be sufficient. In this work we extend the well-known multiparty computation protocol (MPC) for summation of Kurswave . More precisely, we introduce tw

Three-Round Public-Coin Bounded-Auxiliary-Input Zero-Knowledge Arguments of Knowledgeknown that Barak’s non-black-box ZK [FOCS 01], which can be adapted to a ZKAOK, is the first one achieving constant-round, public-coin and strict-polynomial-time simulation properties, and admitting a 6-round implementation shown by Ostrovsky and Visconti [ECCC 12]. This achieves the best exact roun
