J. Mueller-Quade, H. Imai
In this short note we want to introduce {\em anonymous oblivious transfer} a new cryptographic primitive which can be proven to be strictly more powerful than oblivious transfer. W…

Quantum cryptographic three party protocols
J. Mueller-Quade, H. Imai
Due to the impossibility results of Mayers and Lo/Chau it is generally thought that a quantum channel is cryptographically strictly weaker than oblivious transfer. In this paper we…

Temporary Assumptions for Quantum Multiparty Secure Computations
J. Mueller-Quade, H. Imai
This paper introduces quantum multiparty protocols which allow the use of temporary assumptions. We prove that secure quantum multiparty computations are possible if and only if cl…
