摘要
文章基于密文策略的属性加密模式,提出了一种数据资源的安全共享机制,在此安全共享机制中,它为每个数据拥有者定义了相应的数据属性,并为数据共享的不同过程提出了相应算法。为了证明这种共享机制的可行性和有效性,进行了一系列的实验。实验结果表明,在云计算中使用这种机制能够确保数据资源的安全共享。
In order to solve this problem, we propose a secure sharing mechanism which is based on the ciphertext-policy attribute-based encryption scheme （CPA scheme）. In the secure sharing mechanism, the corresponding data attributes are defined for each owner and some corresponding algorithms are proposed for different processes. In order to justify the feasibility and availability of the sharing mechanism, a series of experiments have been done. The results show that it is feasible to ensure the security of data resources sharing in cloud computing.
