Outline of Final Research Achievements

In this research, I proposed a secure file sharing system for cloud storage services with access control by using Ciphertext-Policy Attribute Based Encryption (CP-ABE). The proposed system can protect the contents of files and the file names/directory names, which were not discussed by the past CP-ABE based systems. Moreover, I implemented a prototype system, and evaluated the processing time in order to demonstrate the practicality of the proposed system.
