A　method　of　constructing　a　quantum　hash　function　(QHF)　based　on　continuous-time　quantum　walk　is　proposed,　in　which　the　time　of　quantum　walk　is　controlled　by　the　binary　string　message,　namely,　a　binary　string　message　as　the　input　of　the　constructed　QHF　and　the　probability　value　of　finally　walking　to　the　nodes　on　the　cycle　is　used　as　the　output　of　the　QHF.　Numerical　simulation　and　performance　analysis　show　that　our　QHF　has　obvious　advantages　in　the　efficiency　of　the　QHF　compared　with　the　existing　QHF　based　on　the　discrete-time　quantum　walk,　that　is,　the　efficiency　of　our　scheme　is　nearly　4　times　faster　in　computing　the　hash　value　of　the　same　size　file　compared　with　the　most　efficient　scheme.　Besides,　the　QHF　has　also　better　collision　resistance　compared　with　the　existing　QHF　based　on　the　discrete-time　quantum　walk.
