Abstract. In this paper, we study the security proofs of GCM (Galois/Counter Mode of Operation). We first point out that a lemma, which is related to the upper bound on the probab...

Abstract. Since the appearance of public-key cryptography in the seminal DiffieHellman paper, many new schemes have been proposed and many have been broken. Thus, the simple fact t...

We give an informal analysis and critique of several typical “provable security” results. In some cases there are intuitive but convincing arguments for rejecting the conclusi...

We give an outline of the specification and provable security features of the QUAD stream cipher proposed at Eurocrypt 2006 [6]. The cipher relies on the iteration of a multivaria...

Abstract. Provable security is a very nice property for cryptographic protocols. Unfortunately, in many cases, this is at the cost of a considerable loss in terms of efficiency. Mo...

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...
