Abstract: On modifying Cipher text-Policy Attribute Based Encryption (CP-ABE) and OAuth, we propose a new security scheme, called fuzzy security, to facilitate an application registered with one cloud storage to access data available in cloud storage. The new proposed scheme enables the fuzziness of security to enhance the scalability and flexibility. Also, by conducting attribute distance checking and distance adjustment, operations like sending attribute sets and satisfying an access tree are eliminated. In addition, the automatic revocation is realized with update of Timeslot attribute when data owner modifies the data. In order to make an estimate of the performance of our scheme, we have implemented the protocol flow of fuzzy security with realized cryptographic part with Pairing-Based Cryptography (PBC) library.
