Ensemble Secure Communication Protocol (ESCP) for Data Storage and Retrieval in Private Cloud

摘要

Cloud computing is the recent and thrust research area in the field of information technology. Cloud computing offers a paradigm shift in four major areas such as compute, storage, networking and applications. This research work aims to design and develop the Ensemble Secure Communication Protocol (ESCP) for efficient data storage and retrieval among the private cloud. ESCP has 3 stages. The first conscription stage is used to setup/deploy the private cloud computing environment. The second stage is an authentication and a key sharing stage validates the user with the help of encryption and decryption mechanisms. Finally, at the secure communication stage, the data are stored and retrieved. Matlab tool is used for implementation. Performance metrics such as time taken for encryption, time taken for decryption, overall elapsed time and time taken for data retrieval are taken into account. Performance analysis is also conducted and from the obtained results it is evident that the proposed ESCP outperforms than the existing mechanisms.
