Abstract

In various organizations the demand for the cloud computing going on increasing day by day. That growing acceptance is only due the various services provided by the cloud computing. As the cloud computing provides basic services like allowing for infrastructure sharing , large storage, multi-tenancy which would ultimately leads to increase computational efficiency, flexibility, decrease complexity, and also reduces the data processing cost. But with this, security plays very important role in the success of cloud computing. Most common issues with cloud computing includes data ownership, data privacy and its proper storage for efficient manipulation and updating. Protecting the data of the data owners from an unauthorized users would requires to perform the encryption operation on the entire data and this mechanism increases cost as well as the processing time. Proposed system has some solutions to overcome such problems by using the concept of data classification according to its importance and combined access control with Time and attribute factors for time sensitive data in public cloud. Data get classified according its importance in three categories and the choice of the encryption algorithm will depends on the data importance. That will make the computing efficient. Time and Attribute factors when collectively considered for providing the access control that will provide the data confidentiality, privacy as well as security requirement for time-sensitive data that stored in public cloud. Enhanced security and analysis of system performance proved that proposed system is efficient as well as provides the security requirement for any organization and indivuals.
