Proxy Server for Secure Document Retrieval in Cloud Computing

Authors : R. Kalaiselvi, K. Kousalya and S. Chandramathi

Abstract: Cloud computing is one of the expeditious developing internet qwbased technology that aid users to resort to services by utilizing large pool of resources without installing any software and services available in a pay as-you-go manner. Adopting this technology increases rapidly because of its scalability, elasticity and low cost. As cloud encourages the users to experience its pay per use services, there have been wide privacy concerns in case of data usage. To ensure the security, cloud paradigm allows encrypted format for data storage. To achieve proper encryption and secured data forwarding, cloud can employ proxy server concept. This paper deals with creating a proxy server to view a replicated data document after proper authentication such that the original data in the main server is not accessible that avoids accidental changes and malicious user attacks. Additional security level is incorporated by data re-encryption technique before transmitting encrypted data which resides in server and it also facilitates erasure code for authentication and secured data forwarding. Only after authentication the user can view the desired information completely by receiving key for decrypting the received file. As the user can only get the re-encrypted copy of encrypted data stored by data owner, user cannot modify the original data in the server. The user has only the permission to read the data after the decryption by proper key. This experimental analysis proves that the idea of proxy server provides efficient secure data storage and retrieval.
