Outline of Final Research Achievements

A lot of online storage services, e.g. Dropbox, have been widely used. These services have a weakness, which the storage administrator can obtain contents of user's files. Hence client based encryption systems are used in order to protect user's files on online storage server. In this research, I discuss a file sharing system using Ciphertext-Policy Attribute-Based Encryption (CP-ABE) support for Multi-Authorities.
