在可搜索对称加密(SSE)方案中,客户端可以将加密的文档存储到服务器,使得他可以稍后检索包含特定关键字的加密文档,从而保持关键字和文档的秘密。在本文中,我们展示了如何更新(修改,删除和添加)的文件,在avifiableway。即客户端可以检测到恶意服务器的任何作弊行为。然后,我们证明了我们的计划是UC-安全的标准模型。
In a searchable symmetric encryption (SSE) scheme, a client can store encrypted documents to a server in such way that he can later retrieve the encrypted documents which contain a specific keyword, keeping the keyword and the documents secret. In this paper, we show how to update (modify, delete and add) documents in averifiableway. Namely the client can detect any cheating behavior of malicious servers. We then prove that our scheme is UC-secure in the standard model.
