Abstract. In this paper we present a real-world hardware-assisted attack on the wellknown A5/1 stream cipher which is (still) used to secure GSM communication in most countries all...
Motivated by the goal of factoring large integers using the Number Field Sieve, several special-purpose hardware designs have been recently proposed for solving large sparse system...
