“…Chen et al [17] proposed NCCloud, a proxy-based storage system for fault-tolerant multiple-cloud storage that achieves cost-effective repair for a permanent single-cloud failure. It is built on top of a network-coding-based storage scheme called the functional minimum-storage regenerating (FMSR) codes, which maintain the same fault tolerance and data redundancy as in traditional erasure codes (e.g., RAID-6), but instead it uses less repair traffic which incur less monetary cost due to data transfer.…”

In recent years, cloud computing is highly embraced and considered a must have in the IT world. Cloud computing is a computing paradigm, where a large pool of systems are connected in private, public or hybrid networks, to provide dynamically scalable infrastructure for computing resources. One of the services provided by cloud computing is cloud storage that enables the upload and the retrieval of different kinds of data. Accessing cloud storage service through Internet and pay as you used subscription have been the reasons for the emergence of methods and techniques to effectively store data and reduce storage security vulnerabilities in the cloud storage. This paper provides a survey of some proposed cloud storage methods and techniques, their advantages and drawbacks and makes stress on the current requirements for storage techniques in cloud computing.

“…By striping data across multiple cloud storage vendors, we mitigate the single-point-of-failure and vendor lock-in problems as seen in single-cloud storage. We design and implement NCCloud [1], [3], a proxy system that realizes the benefits of network coding over multiple cloud storage vendors. NCCloud targets long-term archival storage applications, in which data is rarely accessed but needs to be persistently stored for a long period of time.…”

In this paper, we propose a two-factor data security protection mechanism with factor revocability for cloud storage system. Our system allows a sender to send an encrypted message to a receiver through a cloud storage server. The sender only needs to know the identity of the receiver but no other information (such as its public key or its certificate). The receiver needs to possess two things in order to decrypt the ciphertext. The first thing is his/her secret key stored in the computer. The second thing is a unique personal security device which connects to the computer. It is impossible to decrypt the ciphertext without either piece. More importantly, once the security device is stolen or lost, this device is revoked. It cannot be used to decrypt any ciphertext. This can be done by the cloud server which will immediately execute some algorithms to change the existing ciphertext to be un-decryptable by this device. This process is completely transparent to the sender. Furthermore, the cloud server cannot decrypt any ciphertext at any time. The security and efficiency analysis show that our system is not only secure but also practical.
