| Abstract | To assign access privilege for a particular authorized user without disclosing his/her identity for accessing the relevant information and protecting sensitive information from unauthorized access, fine-grained access control for cloud networks is very much essential. Recently many fine grained access control schemes for cloud environments have been proposed in literature using a promising cryptographic solution called attribute-based encryption (ABE). But in a real time scenario, most of them inevitably suffer from lots of serious drawbacks as they are incapable to fulfil some essential security, performance and functionality requirements like user anonymity, users revocation, attributes revocation and user collusion resilience. Moreover these schemes use asymmetric key encryptions which required higher computational cost. In this paper, we present an efficient and secure fine grained access control scheme applicable for cloud networks using symmetric key encryption. Our scheme is able to fulfil fine-grained access control over any type of cloud networks and also ensures that any particular legitimate user can access only that information for which he/she is permitted to access them without compromising user identity. The proposed scheme is resilient against most of all strong attacks such as replay attack and user collusion resilience attack. Moreover our scheme has the provision for user and attributes revocation efficiently. Furthermore, our proposed scheme is light-weight because it uses symmetric key encryption and decryption algorithms. Finally we have shown that our scheme requires lower computation costs and provides higher security compare to other related schemes. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
