With the popularity of wireless communication devices a new important dimension of embedded systems design has arisen, that of security. This paper presents for the first time des...
AVR XMEGA is the recent general-purpose 8-bit microcontroller from Atmel featuring symmetric crypto engines. We analyze the resistance of XMEGA crypto engines to side channel atta...
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...
