In　this　paper　we　analyze　the　security　of　Zhang＇s　scheme　[Chin.　Sci.　Bull.,　2009,　54:　2018-2021],　and　find　that　there　are　two　potential　loopholes,　i.e.　the　participants　forgery　attack　and　impersonation　attack.　Then,　following　the　elementary　method　of　Zhang＇s　scheme,　we　propose　a　quantum　signature-masked　authentication　scheme,　which　can　be　widely　used　many　systems,　such　as　the　identity　authentication　between　Digital　Set-Top-Box　(DSTB)　and　smart　card　in　secure　Digital　Video　Broadcasting　(DVB)　service　system.　In　our　scheme,　a　semi-trusted　center　of　authentication　CA　issues　the　original　credential　certificates　for　a　user　and　the　final　credential　certificates　is　generated　by　adding　her　secret　information,　that　is,　the　user＇s　final　credential　certificates　is　generated　by　her　own　and　CA　together.　This　new　scheme　can　solve　Zhang＇s　scheme　security　problem.　Moreover,　analysis　results　show　that　our　scheme　can　withstand　the　forgery　attack,　impersonation　attack　and　inter-resend　attack.　(C)　2015　Elsevier　GmbH.　All　rights　reserved.
