Secure Data Storage in Cloud
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
Now-a-days, we have the ability to utilize scalable, distributed computing environments within the confines of the Internet, a practice known as cloud computing. Cloud computing can be said as the long term vision of computing as a utility, where the owners of data can remotely store their data in the cloud to enjoy on-demand high-quality applications and services from a shared pool of configurable computing resources. Due to this, many new security challenges, which have not been well understood. This work studies the problem of ensuring the integrity of data storage in Cloud Computing. In this paper, we first design an framework for cloud storage systems and propose an efficient and privacy-preserving auditing protocol. Then, we expand our auditing protocol to support the data dynamic operations, which is efficient and possibly secure in the random oracle model. We expand our auditing protocol to support batch auditing for both multiple owners and multiple clouds, without using any trusted organizer. The simulation results show that our proposed auditing protocols are secure and efficient, especially it reduce the computation cost of the auditor. Such an auditing service not only helps save data owners computation resources but also provides a transparent yet cost-effective method for data owners to gain trust in the cloud. We define different approaches and system requirements that should be brought into consideration, and outline challenges that need to be resolved for such a publicly auditable secure cloud storage service to become a reality.
