Arbitrated Quantum Blind Signature and Its Applications

Abstract

In this thesis we first propose an arbitrated quantum signature (AQS) scheme based on the entanglement swapping of Bell states and two ways for verification: two-step and three-step Through the help of an arbitrator the disputes between participants can be easily resolved Besides based on the AQS scheme we further present the arbitrated quantum blind signature (AQBS) scheme Finally on the basis of the AQBS scheme we propose the arbitrated quantum proxy blind signature (AQPBS) scheme and the quantum anonymous voting system (QVS) The four proposed schemes can not only meet the requirements of different environments but also has the advantage of no need of quantum memory when compared to the existing protocols
