Secure Data Retrieval based on Attribute-based Encryption in Cloud
Cloud computing plays important role in the development of IT industry. It can help a small organization to headway their business. An organization can progress from small scale industry to large scale industry. “Cloud” basically internet based data, network, resource storage. Meanwhile security, integrity, confidentiality requirement need must be achieve by cloud implementation. Attribute base...
متن کاملSecure Data Retrieval Based on Ciphertext Policy Attribute-Based Encryption (CP-ABE) System for the DTNs
Mobile Nodes in some challenging network scenarios suffer from intermittent connectivity and frequent partitions e.g. battlefield and disaster recovery scenarios. Disruption Tolerant Network (DTN) technologies are designed to enable nodes in such environments to communicate with one another. Several application scenarios require a security design that provides fine grain access control to conte...
متن کاملAttribute-Based Encryption: An Efficient Way to Secure Cloud Storage
Cloud computing is an emerging computing paradigm that enables users to remotely store their data on a cloud so as to enjoy scalable services on-demand. It has been found that maintaining the privacy of data from an unauthorized user is really a major challenge. This is a major concern as such data is outsourced to keep storage at third parties say cloud service providers. It is very much essen...
متن کاملSecure Outsourced Attribute-based Encryption
Attribute-Based Encryption (ABE) is a promising cryptographic primitive which significantly enhances the versatility of access control mechanisms. Due to the high expressiveness of ABE policies, the computational complexities of ABE key-issuing (by Attribute Authorities (AAs)) and decryption (by eligible users) are getting prohibitively high. Despite that the existing Outsourced ABE solutions a...
متن کاملDoS-Resistant Attribute-Based Encryption in Mobile Cloud Computing with Revocation
Security and privacy are very important challenges for outsourced private data over cloud storages. By taking Attribute-Based Encryption (ABE) for Access Control (AC) purpose we use fine-grained AC over cloud storage. In this paper, we extend previous Ciphertext Policy ABE (CP-ABE) schemes especially for mobile and resource-constrained devices in a cloud computing environment in two aspects, a ...
