slugEnhanced Privilege Level Wise Access Control for Secure Cloud Storage
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 4
Abstract
Data storage in cloud is possibly a safe and secure way for data accessing and data retrieval, but not at all criteria. Certain security guarantees for the outsourced data were needed to make sure of the access control. To achieve such security goals, many algorithms are used to keep both the data and the key in a secure way. Certain cryptographic key operations using the Advanced Encryption Standard (AES) algorithm were previously implemented that were self- maintained by a quorum of key managers that are independent of third-party clouds. In particular, the work provides insights of how to incorporate value- added security features into today’s cloud storage services. Regarding the enhancement based on improving file access privilege level, Attribute-Based Encryption (ABE) is used in order to improve the security related to the clients/providers accessing the data. Accessing privilege level, like user getting policy base accessing data is concentrated. Accessing level wise is a polynomial interpolation technique, presenting the ABE scheme that can generate security keys of different class for users (like privilege) by integrating cipher text policy attribute- based encryption and hierarchical cryptographic key management. Improvement in the level of security is achieved by handling the key generation technique, using the enhancement made in this paper using ABE.
