Review Paper on Data Access Control using CPABE for Multi-Authority Cloud Storage System
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 4
Abstract
Cloud computing is the system on which we can store data over a network and easily access it from anywhere. But in the case of public cloud storage systems, access control is a most concerning issue[4]. Cipher-text-Policy Attribute-Based Encryption (CP-ABE) is the most excellent technique to provide efficient and secure data access control for public cloud storage. Existing CP-ABE schemes offers single attribute authority to perform user legitimacy verification and also distributing secret keys, and as a result, performance degrades in the case of the large-scale cloud storage system. Users may be a long time waiting to obtain their secret keys, hence efficiency decreases[10]. In this paper, the system employs multiple attribute authorities to share the load of user legitimacy verification. CA (Central Authority) is there to generate secret keys for legitimacy verified users. Each of the authorities in scheme manages the whole attribute set individually. When any user accesses any type of data, AA informs the owner of respective data by a message containing username and details of data that user has been accessed. Auditing mechanism is there to detect which AA (Attribute Authority) is improperly performed the user legitimacy verification procedure.
