Luo Ming-yu, Ling Jie. A Security Cloud Storage Scheme Based on Cipertext Policy Attributebased Encryption[J]. 2014, 31(4): 36-40.DOI: 10.3969/j.issn.1007-7162.2014.04.007.
based on cipertext policy attributebased encryption. A trusted third party was introduced between the terminal and the cloud server in order to solve the problems of large load
heavy burden of key distribution and management. It ensured the data security of the cloud storage system in an incomplete security environment. The results show that it can keep the data security and reduce the load on the terminal
which is in accordance with the developing trend of cloud storage service.
