Performance Analysis of Fragmentation and Replicating Data Over Multi-clouds with Security

In cloud computing, outsourcing a data to third-party cloud providers is not trusted. Ensuring the security is major concern in clouds, our method proposed the security with minimal cryptographic system by fragmenting a data and replicates over Multi-Clouds. We implement RRNS encoding method for fragmenting the data and CTNA which has the centrality measure as a point of distributing and recovering the data. Even in the case of successful attack no information is revealed to anyone. We compute different fragmentation process analysis on several multi-cloud systems, impact in increasing number of nodes, fragments and also the analysis based on different dissemination and retrieval process efficiency with multi-cloud systems. The higher level of security and performance was observed.
