Attribute-Based Encryption: An Efficient Way to Secure Cloud Storage
Rajyalakshmi Jaiswal, A. W. Rohankar · 2013
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 essential to use promising method, which performs encryption on such data before it actually get outsource to the third parties. Besides this, other key issues like - efficient user revocation, scalability in key management; must have to get address while achieving fine grained and scalable access control to cloud storage. This paper ensures effective dealing with above mentioned security concerns by making use of Attribute-Based Encryption technique. Besides this paper presents how cloud storage security is achieved by designing efficient security framework, which is capable of dealing with multiple data owner scenario, handling multiple security domains and dynamic modifications of access policies.
