An operation preceding most human DNA analyses is read mapping, which aligns millions of short sequences (called reads) to a reference genome. This step involves an enormous amount of computation (evaluating edit distances for millions upon billions of sequence pairs) and thus needs to be outsourced to low-cost commercial clouds. This asks for scalable techniques to protect sensitive DNA inform...

This paper explores the privacy of cloud outsourced Model Predictive Control (MPC) for a linear system with input constraints. In our cloud-based architecture, a client sends her private states to the cloud who performs the MPC computation and returns the control inputs. In order to guarantee that the cloud can perform this computation without obtaining anything about the client’s private data,...

Cloud Computing is a virtualized compute power and storage delivered via platform-agnostic infrastructures of abstracted hardware and software accessed over the Internet. Cloud Computing involves delivering hosted services over the internet. These services are broadly categorized into three types, Infrastructure-as-a –Service (IaaS), Platform-as-a-Service(PaaS) and Software-as-a-Service(SaaS). ...

The term data security refers to the degree of resistance of protection given to information from unintended or unauthorized access. The core principles of information security remain the same Confidentiality, Integrity and Availability also referred as CIA triad. With cloud adoption the confidential enterprise data is moved from organization premises to untrusted public network and due to this...

We present PRISM, a privacy-preserving scheme for word search in cloud computing. In the face of a curious cloud provider, the main challenge is to design a scheme that achieves privacy while preserving the efficiency of cloud computing. Solutions from related research, like encrypted keyword search or Private Information Retrieval (PIR), fall short of meeting real-world cloud requirements and ...

Cloud computing is a new design pattern for large, distributed datacenters. Initially, Service providers offering included cloud enabled productivity applications such as search, email, and social networks. Recently they have expanded their offerings to include compute-related capabilities such as virtual machines, storage, and complete operating system services. The cloud computing design yiel...

Cloud storage offers the flexibility of accessing data from anywhere at any time while providing economical benefits and scalability. However, cloud stores lack the ability to manage data provenance. Data provenance describes how a particular piece of data has been produced. It is vital for a post-incident investigation, widely used in healthcare, scientific collaboration, forensic analysis and...

This paper presents Encrypted Cloud (EnCloud), a system designed for providing end-to-end encryption between cloud applications to facilitate their operation and enable users trust in providers. EnCloud relieves end-users’ privacy concerns about the data stored in cloud services so that the private data are securely stored on the cloud server in an encrypted form while the data owner’s EnCloud ...

In this paper we describe our experience in investigating private cloud storage solutions and architectures for long-term data archival storage purpose. The storage solution needs in a campus research environment requires reliability and scalability up to petabytes of data at the minimum. The key requirements for a reliable and scalable cloud storage architecture is discussed below along with p...

51 All Rights Reserved © 2012 IJARCET  Abstract— Hybrid cloud combines the external public services and the internal private cloud providing services thereby enhancing the capabilities to secure, manage and govern the entire cloud spectrum. In this paper, online business management system is implemented using a hybrid cloud architecture which provides faster and greater ease of access to busin...
