Abstract

In this paper, we put forward a weak blind quantum signature scheme based on quantum entanglement swapping of Bell states. Different from the existing quantum signature schemes, our scheme can offer two-step verification security services to ensure the validity of the verification. In order to guarantee the unconditional security of the scheme, the quantum key distribution protocol and one-time pad encryption algorithm are employed in our scheme. Besides, the entanglement swapping of Bell states mechanism enhances the security of verification criteria. The proposed scheme has the properties of nonforgeability, nonrepudiation, blindness, and traceability.

A New Efficient Blind Quantum Signature Scheme Based on Entanglement Swapping

Yun Ting Song

According to the principle of quantum entanglement swapping of GHZ states, this paper put forward a blind signature scheme based on quantum entanglement. Without performing any unitary operation, all participants just need to do Bell measurements on new entangled particles emerging from entanglement swapping of GHZ states to complete blind signature and verification. It is not difficult to prove that the proposed scheme processes the features of nonforgeability, non-disavowal and blindness. Furthermore, compared to some other blind signature schemes on entangled states, our scheme is more efficient because except a few decoy particles, only 2 GHZ states are required for signing each 3 bits in the message.

A Secure Quantum Group Blind Signature Based on Entanglement Swapping

Kai Xing, Rongbo Lu, Juxiu Zhong +1 more

This paper introduces a secure quantum group blind signature (QGBS) based on entanglement swapping. The scheme designed in this article ensures group blind signature and unconditional security by using quantum key distribution (QKD), quantum encryption algorithm, XOR operation and entanglement swapping. The results show that the protocol is not only completely blind, unforgeability, and non-repudiation, but also capable of resisting eavesdropper attacks. In addition, the analysis of the scheme's resistance to various attacks reveals that it demonstrates both efficiency and security.

A weak blind quantum signature protocol based on four-particle cluster state

Minghui-Zhang, Huifang-Li, Yun-Zhou +3 more

In this paper, we introduce the cluster states into the weak blind quantum signature mechanism and put forward a weak blind quantum signature protocol with the four-particle entangled cluster states. The proposed protocol generates four relatively bases to be served as the measurement bases for two- qubit. The employment of QKD protocol and one-time pad encryption algorithm ensure the unconditional security of the protocol. Moreover, we hereinafter prove the security of the protocol against some individual eavesdropping attacks, and we show that our protocol has the characteristics of unforgeability, undeniability, blindness and traceability.

A broadcasting multiple blind signature scheme based on quantum GHZ entanglement

Yuan Tian, Hong Chen, Yan Gao +6 more

Using the correlation of the GHZ triplet states, a broadcasting multiple blind signature scheme is proposed. Different from classical multiple signature and current quantum signature schemes, which could only deliver either multiple signature or unconditional security, our scheme guarantees both by adopting quantum key preparation, quantum encryption algorithm and quantum entanglement. Our proposed scheme has the properties of multiple signature, blindness, non-disavowal, non-forgery and traceability. To the best of our knowledge, we are the first to propose the broadcasting multiple blind signature of quantum cryptography.
