Abstract :In this study, quantum proxy group signature protocol based on the Quantum Fourier Transformation QF T is suggested. In this protocol, QF T is used to share signature with group members. So all proxy group members know only their part of the signature information which are encrypted output of the QF T. This improves the security of the protocol. In addition, the security of the quantum proxy group signature is provided by using reorder QF T output qubits with permutation of the Trent,blinded and nonblinded . The security analysis expresses higher efficiency, effective secret key usage and security of the proposed protocol.
