“…Reading an entire archive, even periodically, greatly limits the scalability of network stores. (The growth in storage capacity has far outstripped the growth in storage access times and bandwidth [44]). Furthermore, I/O incurred to establish data possession interferes with on-demand bandwidth to store and retrieve data.…”

We introduce a model for provable data possession (PDP) that allows a client that has stored data at an untrusted server to verify that the server possesses the original data without retrieving it. The model generates probabilistic proofs of possession by sampling random sets of blocks from the server, which drastically reduces I/O costs. The client maintains a constant amount of metadata to verify the proof. The challenge/response protocol transmits a small, constant amount of data, which minimizes network communication. Thus, the PDP model for remote data checking supports large data sets in widely-distributed storage systems.We present two provably-secure PDP schemes that are more efficient than previous solutions, even when compared with schemes that achieve weaker guarantees. In particular, the overhead at the server is low (or even constant), as opposed to linear in the size of the data. Experiments using our implementation verify the practicality of PDP and reveal that the performance of PDP is bounded by disk I/O and not by cryptographic computation.

“…Gurumurthi and Sivasubramaniam [2006] reported that within the thermal envelope, the response time of real workloads can be improved by 30-60% with a 10K increase of the RPM. Unfortunately, the disk drives rotating at speeds exceeding 20, 000 RPM have been researched but not commercialized due to heat generation, power consumption, noise, vibration and other problems in characteristics, and a lack of long term reliability [Thompson and Best 2000]. Therefore, it is a big challenge to design new disk drive architecture which could further advance disk performance.…”

________________________________________________________________________Disk drives have experienced dramatic development to meet the performance requirements, since the IBM 1301 disk drive was announced in 1961. However, the performance gap between memory and disk drives has widened to 6 orders of magnitude and continues to widen by about 50% per year. Furthermore, energy efficiency has become one of the most important challenges in designing disk drive storage systems. The architectural design of disk drives has reached a turning point which should allow their performance to advance further, while still maintaining high reliability and energy efficiency. This paper explains how disk drives have evolved over five decades to meet challenging customer demands. First of all, it briefly introduces the development of disk drives, and deconstructs disk performance and power consumption. Secondly, it describes the design constraints and challenges that traditional disk drives are facing. Thirdly, it presents some innovative disk drive architectures discussed in the community. Fourthly, it introduces some new storage media types and the impacts they have on the architecture of the traditional disk drives. Finally, it discusses two of the important evolutions of the disk drives: hybrid disk and solid state disk. The paper highlights the challenges and opportunities facing these storage devices, and explores how we can expect them to affect the storage systems.

“…When this happens, the information stored in the particle randomly reverses itself at a rate far higher than that needed to provide reliable storage. There are a few techniques being researched as a means of staving off the superparamagnetic effect as long as possible 2 , but increases in performance beyond another order of magnitude are not expected to materialize [35].…”

There are several engineering obstacles that need to be solved before key management and encryption under the bounded storage model can be realized. One of the critical obstacles hindering its adoption is the construction of a scheme that achieves reliable communication in the event that timing synchronization errors occur. One of the main accomplishments of this project was the development of a new scheme that solves this problem. We show in general that there exist message encoding techniques under the bounded storage model that provide an arbitrarily small probability of transmission error. We compute the maximum capacity of this channel using the unsynchronized key-expansion as side-channel information at the decoder and provide tight lower bounds for a particular class of key-expansion functions that are pseudo-invariant to timing errors. Using our results in combination with Dziembowski et al.[11] encryption scheme we can construct a scheme that solves the timing synchronization error problem.In addition to this work we conducted a detailed case study of current and future storage technologies. We analyzed the cost, capacity, and storage data rate of various technologies, so that precise security parameters can be developed for bounded storage encryption schemes. This will provide an invaluable tool for developing these schemes in practice.3 4
