Cloud computing is associate coming paradigm that gives tremendous benefits in economical aspects, resembling reduced time to promote, versatile computing capabilities, and limitless computing power. To use the complete potential of cloud computing, knowledge is transferred, processed and hold on by external cloud suppliers. However, data owners are very skeptical to place their data outside their own control sphere. Cloud computing is a new development of grid, parallel, and distributed computing with visualization techniques. It is changing the IT industry in a prominent way. Cloud computing has grown due to its advantages like storage capacity, resources pooling and multi-tenancy. In the proposed system, data to be send to the cloud is encrypted in two steps which are transposition cipher and by encrypting dynamic chunks in lesser time. Proposed system is also evaluated on various parameters like encryption time and data migration time. When compared it is seen that the performance of the proposed system is better than that of existing parameters in terms of evaluating parameters.
