Abstract

Cloud computing is the buzz word in the today’s information technology arena and thrust research area due to its wide range in offering services. Ensuring security is the ever demanding research problem in private cloud environment. This research work aims in proposing improved security mechanism which is based on advanced encryption standard algorithm. A decisive method is used in order to verify the security of data packets. Then by making use of distributed data storage mechanism the data is stored in the private cloud servers. Undemanding data retrieval is used for obtaining the data back for the user. Simulations are carried out using MATLAB. Performance metrics such as time taken for encryption, time taken for decryption, overall elapsed time and time taken for data retrieval are chosen. From the results it is evident that the proposed D2S2M outperforms the other existing methods.
