ETHTID: Deployable Threshold Information Disclosure on Ethereum
Oliver Stengele, Markus Raiber, Jörn Müller-Quade +1
We address the Threshold Information Disclosure (TID) problem on Ethereum: An arbitrary number of users commit to the scheduled disclosure of their individual messages recorded on…
On the Composability of Statistically Secure Random Oblivious Transfer
Rafael Dowsley, Jörn Müller-Quade, Anderson C. A. Nascimento
We show that stand-alone statistically secure random oblivious transfer protocols based on two-party stateless primitives are statistically universally composable. I.e. they are si…
Weakening the Isolation Assumption of Tamper-proof Hardware Tokens
Rafael Dowsley, Jörn Müller-Quade, Tobias Nilges
Recent results have shown the usefulness of tamper-proof hardware tokens as a setup assumption for building UC-secure two-party computation protocols, thus providing broad security…
Composability in quantum cryptography
Joern Mueller-Quade, Renato Renner
In this article, we review several aspects of composability in the context of quantum cryptography. The first part is devoted to key distribution. We discuss the security criteria…
Cryptanalysis of a Practical Quantum Key Distribution With Polarization-Entangled Photons
Thomas Beth, Joern Mueller-Quade, Rainer Steinwandt
Recently, a quantum key exchange protocol has been described, which served as basis for securing an actual bank transaction by means of quantum cryptography [quant-ph/0404115]. Her…
A Quantum Information Theoretical Model for Quantum Secret Sharing Schemes
Hideki Imai, Joern Mueller-Quade, Anderson C. A. Nascimento +2
In this paper we introduce a quantum information theoretical model for quantum secret sharing schemes. We show that quantum information theory provides a unifying framework for the…
