As data storage needs increase, importance of and need for public cloud storage systems increase as well. However, given the amount, variety and importance of the data security can become a significant concern. Attribute based encryption schemes are important tools that can be used for access control in secure cloud storage systems. There are many attribute based encryption schemes proposed overs the years; key policy, ciphertext policy and multi-authority schemes. It is important to choose the most suitable attribute based encryption scheme to use in secure cloud storage systems. In this work, we investigate which Attribute Based Encryption Scheme would be suitable to use in a global scale secure cloud storage system. We analyze 5 different Attribute Based Encryption Schemes about; how they work, usage of pairings and suitability global scale secure cloud storage systems. After choosing the most suitable scheme we then discuss how we can improve performance of this scheme.

Optimal dynamic resource allocation for heterogenous cloud data centers
Ekici, Nazım Umut; Güran Schmidt, Şenan.; Department of Electrical and Electronics Engineering (2019)
Today's data centers are mostly cloud-based with virtualized servers to provide on-demand scalability and flexibility of the available resources such as CPU, memory, data storage and network bandwidth. Heterogeneous cloud data centers (CDCs) offer hardware accelerators in addition to these standard cloud server resources. A cloud data center provider may provide Infrastructure as a Service and Platform as a Service (IPaaS), where the user gets a virtual machine (VM) with processing, memory, storage and netw...
Hierarchical Coding for Cloud Storage: Topology-Adaptivity, Scalability, and Flexibility
Yang, Siyi; Hareedy, Ahmed; Calderbank, Robert; Dolecek, Lara (2022-06-01)
In order to accommodate the ever-growing data from various, possibly independent, sources and the dynamic nature of data usage rates in practical applications, modern cloud data storage systems are required to be scalable, flexible, and heterogeneous. The recent rise of the blockchain technology is also moving various information systems towards decentralization to achieve high privacy at low costs. While codes with hierarchical locality have been intensively studied in the context of centralized cloud stor...
Hierarchical coding to enable scalability and flexibility in heterogeneous cloud storage
Yang, Siyi; Hareedy, Ahmed; Calderbank, Robert; Dolecek, Lara (2019-12-01)
In order to accommodate the ever-growing data from various, possibly independent, sources and the dynamic nature of data usage rates in practical applications, modern cloud data storage systems are required to be scalable, flexible, and heterogeneous. Codes with hierarchical locality have been intensively studied due to their effectiveness in reducing the average reading time in cloud storage. In this paper, we present the first codes with hierarchical locality that achieve scalability and flexibility in he...
A Joint resource allocation system for cloud computing /
Dikbayır, Hüseyin Seçkin; Bazlamaçcı, Cüneyt Fehmi; Department of Electrical and Electronics Engineering (2014)
Cloud computing is a new trend in computing, where resources such as servers, storage devices and software applications are provided to customers over the Internet. It is typically based on a pay-per-use model similar to renting a car or taking a taxi in our daily life. The primary purpose of a cloud system is to utilize available resources effectively to provide an economic benefit to customers. To succeed in this, jobs initiated by consumers are allocated to a set of virtual machines (VM) that run in big ...
Minimizing the Number of Detrimental Objects in Multi-Dimensional Graph-Based Codes
Hareedy, Ahmed; Kuditipudi, Rohith; Calderbank, Robert (2020-09-01)
© 1972-2012 IEEE.The increasing demand for access to data has led to dramatic increases in data storage densities, and as densities increase, new sources of error appear. Multi-dimensional (MD) graph-based codes are capable of mitigating error sources like interference and channel non-uniformity in dense storage devices. A recent innovation improves the performance of MD spatially-coupled codes that are based on circulants by carefully relocating some circulants to minimize the number of short cycles. Howev...
