This paper establishes a novel model for RFID schemes where readers are not continuously connected to the back office, but only periodically. Furthermore, adversaries are not only ...
Abstract. Direct Anonymous Attestation (DAA) is an anonymous digital signature scheme that aims to provide both signer authentication and privacy. One of the properties that makes ...
In this paper we describe a simple protocol for secure delegation of the elliptic-curve pairing. A computationally limited device (typically a smart-card) will delegate the computa...
Let n be an RSA modulus and let P, Q ∈ (Z/nZ)[X]. This paper explores the following problem: Given polynomials Q and Q(P), find polynomial P. We shed light on the connections be...
At ACISP 2004, Giraud and Knudsen presented the first fault analysis of DSA, ECDSA, XTR-DSA, Schnorr and ElGamal signatures schemes that considered faults affecting one byte. The...
