A quantum proxy group signature scheme is proposed with χ-type entangled states. Our scheme combines the properties of group signature and proxy signature. Moreover, the particles in the χ-type state sequence are used to distribute proxy warrants and quantum keys in the initial phase, and then used for quantum signature. Therefore it increases the utilization rate of quantum resources compared with the general quantum signature scheme. Finally, the unconditional security of our scheme is also analyzed.
