Motivated　by　the　dense　coding　and　teleportation　of　two-mode　squeezed　vacuum　(TMSV)　state,　a　continuous-variable　arbitrated　quantum　signature　(CV-AQS)　scheme　is　proposed.　The　signer　Alice　generates　the　signature　by　the　dense　coding　and　sends　it　to　the　verifier　Bob.　The　measurement　results　of　two　quadrature　components　serve　for　the　recovery　of　the　secret　message.　With　the　help　of　the　arbitrator　Charlie,　Bob　verifies　the　validity　of　the　signature.　The　security　of　the　presented　protocol　is　protected　by　the　calculation　of　the　fidelity　parameter　and　the　implementation　process　of　two-mode　squeezed　vacuum　(TMSV)　state　teleportation.　Moreover,　the　proposed　scheme　can　be　correctly　implemented　in　the　lossy　and　lossless　transmission　with　a　higher　capacity.
