Public　key　encryption　with　keyword　search　enables　users　to　retrieve　keywords　from　encrypted　data,　which　can　protect　data　confidentiality　without　losing　the　search　operability.　However,　it　is　also　vulnerable　to　keyword　guessing　attacks.　In　this　paper,　we　propose　a　conjunctive　keywords　searchable　encryption　with　designated　tester　(dPECK)　to　prevent　the　keyword　guessing　attacks.　It　can　support　multiple-keywords　query　at　one　time,　i.e.　conjunctive　keywords　search.　We　formulate　the　security　notions　for　the　conjunctive　keyword　search　with　the　designated　tester　and　present　an　efficient　scheme　which　is　proven　secure　in　the　standard　model.　Moreover,　we　extend　the　dPECK　to　proxy　re-encryption　dPECK　(Re-dPECK)　in　order　to　enable　the　search　proxy　function.　At　last,　the　comparison　and　efficiency　simulation　demonstrates　that　this　scheme　has　the　lower　computation　and　storage　overhead.　©　2013　IEEE.
