摘要：
In this paper, a secure quantum proxy group signature (QPGS) scheme based on three-qubit entangled states is proposed. The three-qubit entangled state functions as a quantum channel, conserving entanglement resources more effectively than similar papers that have been proposed. The properties of proxy signature and group signature are satisfied at the same time. In this scheme, quantum one-time pad (QOTP) methods and eavesdropping detection techniques with quantum properties are adopted. In addition, the security analysis of this scheme shows that our scheme has unforgeability and undeniability as well as resistance to some existing attacks. The QPGS has the potential to be used in scenarios where representative signatures of group members are required, and privacy protection is needed.
