A Trusted Third-Party E-Payment Protocol Based on Quantum Blind Signature Without Entanglement

In this paper, we present a trusted third-party e-payment protocol which is designed based on quantum blind signature without entanglement. The security and verifiability of our scheme are guaranteed by using single-particle unitary operation, quantum key distribution (QKD) protocol and one-time pad. Furthermore, once there is a dispute among the participants, it can be solved with the assistance of the third-party platform which is reliant.     

An Elaborate Secure Quantum Voting Scheme

An elaborate secure quantum voting scheme is presented in this paper. It is based on quantum proxy blind signature. The eligible voter’s voting information can be transmitted to the tallyman Bob with the help of the scrutineer Charlie. Charlie’s supervision in the whole voting process can make the protocol satisfy fairness and un-repeatability so as to avoid Bob’s dishonest behaviour. Our scheme uses the physical characteristics of quantum mechanics to achieve voting, counting and immediate supervision. In addition, the program also uses quantum key distribution protocol and quantum one-time pad to guarantee its unconditional security.

An Improved Proxy Blind Signature Scheme

In this paper, we propose an improved proxy blind signature scheme based on controlled quantum teleportation. Five-qubit entangled state functions as quantum channel. We use physical characteristics of quantum mechanics to implement signature, delegation and verification. Furthermore, quantum key distribution (QKD) protocol and one-time pad are adopted in this scheme. Like classical signature protocols, our scheme can be used in many application scenarios, such as e-government and e-business.

     

A Choreographed Distributed Electronic Voting Scheme

In this paper, we propose a choreographed distributed electronic voting scheme, which is based on quantum group blind signature. Our distributed electronic voting scheme could really protect the message owner’s privacy and anonymity which the classical electronic voting systems can not provide. The electors can exercise their voting rights effectively, and no one other than the tallyman Bob knows the contents of his vote. Moreover, we use quantum key distribution protocol and quantum one-time pad to guarantee its unconditional security. Furthermore, when there was a dispute, the group supervisor David can detect the source of the signature based on the signature’s serial number \(SN\).     

A Quantum Proxy Blind Signature Scheme Based on Genuine Five-Qubit Entangled State

In this paper, a quantum proxy blind signature scheme based on controlled quantum teleportation is proposed. This scheme uses a genuine five-qubit entangled state as quantum channel and adopts the classical Vernam algorithm to blind message. We use the physical characteristics of quantum mechanics to implement delegation, signature and verification. Security analysis shows that our scheme is valid and satisfy the properties of a proxy blind signature, such as blindness, verifiability, unforgeability, undeniability.
