Abstract. Inthis paper we present several weaknesses in the keyscheduling algorithm of RC4, and describe their cryptanalytic signi cance. We identify a large number of weak keys, i...
Non-interactive zero-knowledge proofs play an essential role in many cryptographic protocols. We suggest several NIZK proof systems based on prime order groups with a bilinear map...
We consider the problem of computing the intersection of private datasets of two parties, where the datasets contain lists of elements taken from a large domain. This problem has m...
Field Programmable Gate Arrays (FPGAs) are an increasingly popular choice of platform for the implementation of cryptographic systems. Until recently, designers using FPGAs had le...
Electronic Payments have gained tremendous popularity in the modern world. Credit/debit cards and online payments are in widespread use. Bringing electronic payments to the mobile...
