Attribute Based Encryption

From the time in memorial, Information Security has remained a primary concern and today when most of the sensitive data is stored on Cloud with client organization having lesser control over the stored data, the fundamental way to fix this issue is to encrypt such data. So, a secure user imposed data access control system must be given, before the users outsource any data to the cloud for storage. Attribute Based Encryption (ABE) system is one such asymmetric key based cryptosystem that has received much attention that provides fine-grained access control to data stored on the cloud. In this paper, we propose a more proficient and richer type of Attribute Based Encryption technique (RSABE) that not only considers the Outsourced ABE construction but also address the issue of revocation in case of change of attributes of the group user or organization; once a user is removed from the group, the keys are updated and these new keys are distributed among the existing users also our system supports the Keyword search over encrypted data in the mobile cloud storage. In multi keyword search; data owners and users can generate the keywords index and search trapdoor, respectively, without relying on always online trusted authority. Experimental results prove that the performance of the proposed system is greater than existing system in terms of security, time consumption and memory utilization & data availability.
