A Hardware-Assisted Realtime Attack on A5/2 Without Precomputations
Abstract. A5/2 is a synchronous stream cipher that is used for protecting GSM communication. Recently, some powerful attacks [2,10] on A5/2 have been proposed. In this contribution...

Enabling Full-Size Public-Key Algorithms on 8-Bit Sensor Nodes
Abstract. In this article we present the fastest known implementation of a modular multiplication for a 160-bit standard compliant elliptic curve (secp160r1) for 8-bit micro contro...

The Power of Proofs-of-Possession: Securing Multiparty Signatures against Rogue-Key Attacks
Abstract. Multiparty signature protocols need protection against roguekey attacks, made possible whenever an adversary can choose its public key(s) arbitrarily. For many schemes, p...
