A NOVEL APPROACH OF HYBRID MODEL OF ENCRYPTION ALGORITHMS AND FRAGMENTATION TO ENSURE CLOUD SECURITY

Cloud is a term used as a metaphor for the wide area networks (like internet) or any such large networked environment. It came partly from the cloud-like symbol used to represent the complexities of the networks in the schematic diagrams. It represents all the complexities of the network which may include everything from cables, routers, servers, data centers and all such other devices. Cloud based systems saves data off multiple organizations on shared hardware systems. Data segregation is done by encrypting data of users, but encryption is not complete solution. In the proposed work, we have tried to increase the cloud security by using encryption algorithms like AES and RSA along with OTP authentication. We have also fragmented the data by using data distribution at the server end.
