Secure cloud storage

We describe, at a high level, several architectures that combine recent and non-standard cryptographic primitives in order to achieve our goal. We survey the benefits such an architecture would provide to both customers and service providers and give an overview of recent advances in cryptography motivated specifically by cloud storage. | ISSN:2249-5789 Mahima Joshi et al, International Journal of Computer Science & Communication Networks,Vol 1(2), 171-175 SECURE CLOUD STORAGE Mahima Joshi, Yudhveer Singh Moudgil Computer Science and Engineering Department Uttaranchal Institute of Technology, Dehradun Mahima_joshi2003@yahoo.com,Yudhveer127@gmail.com control). In particular, this means that access to Abstract As an emerging technology and business paradigm, Cloud Computing has taken commercial computing by storm. Cloud computing platforms provide easy access to a company’s high-performance computing and storage infrastructure through web services. We consider the problem of building a secure cloud storage service on top of a public cloud infrastructure where the service provider is not completely trusted by the customer. We describe, at a high level, several architectures that combine recent and non-standard cryptographic primitives in order to achieve our goal. We survey the benefits such an architecture would provide to both customers and service providers and give an overview of recent advances in cryptography motivated specifically by cloud storage. Keywords-cloud computing, cloud architecture, cryptographic key, token. customer data is under its control and is only granted to parties it trusts. In a public cloud the infrastructure is owned and managed by a cloud service provider and is located on premise (i.e., in The service provider's region of control). This means that customer data is outside its control and could potentially be granted to untrusted parties. storage, 1. Introduction Cloud computing portends a major change in how to store information and run applications. Instead of running programs and data on an individual desktop computer, everything is hosted in the “cloud”—a nebulous assemblage of computers and servers accessed via the Internet. Cloud computing lets you access all your applications and documents from anywhere in the world, freeing you from the confines of the .
