The intermediate communication nodes are allowed by network coding to encode the received data. Moreover, it has been confirmed that the upper limit of the communication network capacity can be achieved, which is conducive to improving the throughput of the communication network, but it is vulnerable to pollution attacks when the classic channels are used as the auxiliary resources. Although the quantum network coding can be used to increase the transmission speed of quantum bits per unit time based on the existing channels, the same security problems have arisen from quantum network coding in terms of the pollution attacks. In this paper, based on the anti-pollution characteristics of quantum signatures, a kind of quantum blind signature network coding scheme is put forward. Since various performances of the signature added in the process of data transmission will be improved, the blind signature is added at the intermediate node of the secure butterfly network and the data has been blinded by means of the quantum entanglement characteristics, yet the data of the intermediate node data packet has not been changed. According to the analysis results, it has defended against pollution attacks with high fidelity, low resource consumption, and low rate area.
