报告摘要:Cloud computing can shift the burden of maintaining a large number of files from the owner to proxy servers. In practice, the original files will be removed by the owner for the sake of space efficiency. Hence, the issues on confidentiality and integrity of the outsourced data must be addressed carefully. In this talk, I will introduce two identity-based data storage schemes with the following properties: (1) File-based access control; (2) Supporting both intra-domain and inter-domain queries.
