| 摘 要： | Dan Boneh等人提出了具有关键词搜索性质的公钥加密方案,并且构造出了在随机预言模型下可证明安全的基于BDH困难问题的双线性映射对下的具体构造.本文给出了一个具有关键字搜索性质的高效云存储加密方案,而且在随机预言模型下可证明CCA-安全.该方案能够安全高效的管理云服务器中的加密文件,能够对已经加密的文件进行相等配对.构造方案能够在无安全信道环境中传输陷门Tw.

| Abstract: | The public key encryption with keyword search （PEKS） scheme proposed by Boneh, Dan. They constructe PEKS scheme using Bilinear Maps in the random oracle model which this scheme is based on the Computational Diffie-Hellman problem. In this paper, we give the definition and security model of Cloud Storage Encryption with Keyword Search Scheme which is proven under CCA_secure in the random oracle model. This mechanism can manage encrypted file in cloud server safety and test equal between key and encrypted file. The construction can make Tw transmission without Secure Channel. |
