Cloud computing security analysis based on RC6, AES and RSA algorithms in user-cloud environment

In this paper a cloud computing security analysis based on RC6, AES and RSA algorithms in client-cloud environment has proposed. This framework is divided in 2 phases. Data pre-processing is first phase applied based on the weight assigned. Based on the data values obtainable from the uploaded textual file in cloud environment weight assigned is calculated. Now in second phase fuzzy c-means has been applied in cloud on the uploaded data for clustering. First the score in terms of aggregated assessment ranking have been calculated based on simple additive weighting (SAW). Then the decision performances have been arranged. Different random sets of data values have been obtained and also the aggregated values have been obtained. These aggregated sets will determine the security operation and the risk associated with the data uploaded with the cloud environment. The maximum key unpredictability and validation shows the privileged security in terms of the elevated threat opportunity. Proposed automated FCM based clustered and multi layer security standard algorithms have potential to deal with multifaceted security.
