Cluster　states　can　be　exploited　for　some　tasks　such　as　topological　one-way　computation,　quantum　error　correction,　teleportation　and　dense　coding.　In　this　paper,　we　investigate　and　propose　an　arbitrated　quantum　signature　scheme　with　cluster　states.　The　cluster　states　are　used　for　quantum　key　distribution　and　quantum　signature.　The　proposed　scheme　can　achieve　an　efficiency　of　100　%.　Finally,　we　also　discuss　its　security　against　various　attacks.
