Quantum　network　coding　(QNC)　is　expected　to　enable　multiple　quantum　data　packets　to　be　fused　before　the　transmission　via　the　bottleneck　channel　in　order　to　improve　the　transmission　efficiency　and　the　total　throughput　of　quantum　networks.　Although　several　QNC　schemes　have　been　constructed,　they　are　unable　to　meet　the　practical　application　requirements　due　to　the　fact　that　they　lack　a　complete　security　solution.　To　tackle　this　issue,　a　practical　secure　QNC　scheme　is　constructed.　Compared　with　existing　methods,　the　proposed　QNC　scheme　is　more　practical　and　most　importantly　it　can　provide　complete　security　against　both　information　leakage　and　pollution　attacks,　which　greatly　contributes　to　global　quantum　communication　networks.
