摘要

针对云存储的数据安全共享及效率问题，提出一种实用的云存储系统方案。方案使用对称加密和属性加密，融入代理加密功能，实现加密保护、访问控制和高效检索的无缝结合。基于双线性映射和多项式方程技术，实现连接关键词非域子集搜索。基于外包解密技术，将原属于用户完成的部分解密工作转移到云端服务器完成，降低解密带来的计算开销。对方案的性能进行了分析，并通过实验验证。

Abstract

A practical scheme for the cloud storage system was proposed to ensure security and efficiency during data sharing.The scheme which combine attribute-based encryption

proxy encryption with symmetric encryption

could integrate access control

efficient search with encryption well together.The scheme archived conjunctive-keyword non-field subset search by using bilinear mapping and polynomial equation.The scheme reduced the cost of decryption by outsourcing most of the decryption operations from the terminal to the cloud.At last

the performance was analyzed and an experiment was made for verification.
