ANALYSIS IN CLOUD COMPUTING ACCESS CONTROL ISSUES

Distributed computing is the utilization of registering assets like equipment and programming that are conveyed as an administration over a system. It trusts remote administrations with a client's information and programming, it empowers a client to do substantial measure of capacity, huge measure of calculations. Because of which information security in cloud turns into a major issue. Information get to control gives the security of information in the cloud. The vast measure of information outsourced in cloud servers, the information get to control turns into a testing issue in distributed storage frameworks. We have many access control security arrangements like Attribute based, Role based, Hierarchical character administration, Identity based validation, Trust based model and so on. Distributed computing is one late advancements. So it moves toward becoming exceptionally important to secure the information and also protection of clients. Access Control strategies give a compelling approach to guarantee that approved client's entrance the information and the framework. In this paper we talked about different highlights of quality based Encryption, Role based, Hierarchical personality administration, Identity based confirmation, Trust based model reasonable for distributed computing condition

Managing Access to Service Providers in Federated Identity Environments: A Case Study in a Cloud Storage Service

© 2015 IEEE. Currently the diversity of services, which are adhering to Identity Federation, has raised new challenges in the area. Increasingly, service providers need to control the access to their resources by users from the federation as, even though the user is authenticated by the federation, its access to resources cannot be taken for granted. Each Service Provider (SP) of a federation implements their own access control mechanism. Moreover, SPs might need to allow different access control granularity. For instance, all users from a particular Identity Provider (IdP) may access the resources due to some financial agreement. On the other hand, it might be the case that only specific users, or groups of users, have access to the resources. This paper proposes a solution to this problem through a hierarchical authorization system. Our approach, which can be customized to different SPs, allows the SP administrator to manage which IdPs, or users, have access to the provided resources. In order to demonstrate the feasibility of our approach, we present a case study in the context of a cloud storage solution

Secure data sharing and processing in heterogeneous clouds

The extensive cloud adoption among the European Public Sector Players empowered them to own and operate a range of cloud infrastructures. These deployments vary both in the size and capabilities, as well as in the range of employed technologies and processes. The public sector, however, lacks the necessary technology to enable effective, interoperable and secure integration of a multitude of its computing clouds and services. In this work we focus on the federation of private clouds and the approaches that enable secure data sharing and processing among the collaborating infrastructures and services of public entities. We investigate the aspects of access control, data and security policy languages, as well as cryptographic approaches that enable fine-grained security and data processing in semi-trusted environments. We identify the main challenges and frame the future work that serve as an enabler of interoperability among heterogeneous infrastructures and services. Our goal is to enable both security and legal conformance as well as to facilitate transparency, privacy and effectivity of private cloud federations for the public sector needs. © 2015 The Authors

AnonyControl: Control Cloud Data Anonymously with Multi-Authority Attribute-Based Encryption

Cloud computing is a revolutionary computing paradigm which enables flexible, on-demand and low-cost usage of computing resources. However, those advantages, ironically, are the causes of security and privacy problems, which emerge because the data owned by different users are stored in some cloud servers instead of under their own control. To deal with security problems, various schemes based on the Attribute- Based Encryption (ABE) have been proposed recently. However, the privacy problem of cloud computing is yet to be solved. This paper presents an anonymous privilege control scheme AnonyControl to address the user and data privacy problem in a cloud. By using multiple authorities in cloud computing system, our proposed scheme achieves anonymous cloud data access, finegrained privilege control, and more importantly, tolerance to up to (N -2) authority compromise. Our security and performance analysis show that AnonyControl is both secure and efficient for cloud computing environment.Comment: 9 pages, 6 figures, 3 tables, conference, IEEE INFOCOM 201

A systematic literature review of cloud computing in eHealth

Cloud computing in eHealth is an emerging area for only few years. There needs to identify the state of the art and pinpoint challenges and possible directions for researchers and applications developers. Based on this need, we have conducted a systematic review of cloud computing in eHealth. We searched ACM Digital Library, IEEE Xplore, Inspec, ISI Web of Science and Springer as well as relevant open-access journals for relevant articles. A total of 237 studies were first searched, of which 44 papers met the Include Criteria. The studies identified three types of studied areas about cloud computing in eHealth, namely (1) cloud-based eHealth framework design (n=13); (2) applications of cloud computing (n=17); and (3) security or privacy control mechanisms of healthcare data in the cloud (n=14). Most of the studies in the review were about designs and concept-proof. Only very few studies have evaluated their research in the real world, which may indicate that the application of cloud computing in eHealth is still very immature. However, our presented review could pinpoint that a hybrid cloud platform with mixed access control and security protection mechanisms will be a main research area for developing citizen centred home-based healthcare applications
