Abstract: A secured data sharing algorithm is implemented across the dynamic users in the cloud using an efficient attribute based cryptography technique. The proposed data sharing algorithm provides two solutions to the effective usage of resources to the organisational data storage. Initially, E-ABBE scheme and the latter group-based ABE technique help to provide a flexible, confidential and easy key management method. The overhead of computation will still be constant and will not take account of the number of users and revoked users in the group which ensures privacy and security to utilise the cloud resources by the group users; these solutions are applied for agriculture data in an agri-cloud drive for such dynamic groups using techniques. The performance analysis of the proposed method has been assessed by simulating it in Cloud Sim tool and the results are compared with MONA.

Keywords: data sharing; cloud computing; key management; dynamic groups; multiple owners; cloud computing; agri-cloud; attribute-based encryption; attribute-based group signature.
