In this paper, an improved TSZ scheme was proposed by using oblivious polynomial evaluation (OPE) protocol and service parameters. Under the recondition of general sameness capabilities of both TSZ and improved TSZ scheme, the new scheme adds some advantages such as providing multi-service capability, user's non-repudiation and data provider's no-framing innocent users. Furthermore, it is also proved to be semantically secure under the decisional bilinear Diffie-Hellman (DBDH problem) assumption.展开更多
