An Effective Data Storage Security Scheme for Cloud Computing

Kalpana Batra, Ch. Sunitha, Sushil Kumar

Cloud computing has been envisioned as the next generation information technology architecture for enterprises. Cloud Computing moves the data on the cloud storage servers maintained by service providers, which deprive the user of their control of the physical possession of data, even though they are the owners of the data. This unique feature however has raised many new security challenges which have not been well understood. In this paper we focus on cloud data storage security, which is an important aspect of Quality of service. We introduced an effective and flexible distribution verification mechanism to address data storage security in cloud computing. In this mechanism, we rely on token pre-computation to verify the correctness coded data rather than Pseudorandom Data. We present the system with design goals of Storage correctness and Fast Localization of Data Errors.
