A group signature scheme based on quantum teleportation

Abstract

In this paper, we present a group signature scheme using quantum teleportation. Different from classical group signature and current quantum signature schemes, which could only deliver either group signature or unconditional security, our scheme guarantees both by adopting quantum key preparation, quantum encryption algorithm and quantum teleportation. Security analysis proved that our scheme has the characteristics of group signature, non-counterfeit, non-disavowal, blindness and traceability. Our quantum group signature scheme has a foreseeable application in the e-payment system, e-government, e-business, etc.

Quantum Secure Communication Protocol with Signature

“…Their scheme can be used to sign general quantum superposition states. To protect the privacy of message owners, Wen et al [45] proposed the first quantum group signature scheme by using quantum teleportation. In order to authenticate the identity of different data source in a network, homomorphic signature scheme [46] is considerably paid attention to instead of standard signature schemes in classical cryptography.…”

A chaos-based quantum group signature scheme in quantum cryptosystem

“…With the development of quantum cryptography, some quantum group signature (QGS) schemes have recently been introduced to ensure security. A pioneering QGS protocol was proposed by WEN et al [6]. In their scheme, the group manager is simply considered the arbitrator and the technique of teleportation is implemented to verify the validity of the signature.…”

Quantum Signature Scheme Using a Single Qubit Rotation Operator

“…Since then, various quantum signature schemes (such as quantum proxy signatures, quantum group signatures, quantum blind signatures, quantum multiparty signatures, etc.) have been proposed [25][26][27][28][29][30][31][32][33][34].…”
