Access Control based Efficient Hybrid Security Mechanisms for Cloud Storage

Providing security to the cloud data is a highly complicated and demanding task nowadays. For this purpose, different existing works provide encryption and key generation based techniques during cloud data sharing. But, it has some major drawbacks such as, inefficient computation, increased time consumption, and requires more storage space. The cost of maintenance of data over the cloud could be considered and hence this paper presents a cost efficient and reliable data hosting scheme called, Hybrid cryptography which provides systematic architecture with distributed data hosting in the heterogeneous cloud infrastructure SMS to transit the data files to optimize both bandwidth and speed. The proposed system considers data migration within the cloud system with respect to the cost of migration and the data access patterns. For experimental results, the performance of the suggested technique is evaluated based on the measures of encryption time, decryption time, and key generation time.
