HASBE: A Hierarchical Attribute Set Based Encryption For Flexible, Scalable And Fine Grained Access Control In Cloud Computing
Journal Title: International Journal of Computer & organization Trends(IJCOT) - Year 2013, Vol 3, Issue 9
Abstract
At present cloud computing is going to be very famous technology in IT enterprises. For a company, the data stored is huge and it is very precious. All functions are performed through networks. Thus, it becomes very important to have the secured use of data. In cloud computing, the ultimate important concerns of security are data security and confidentiality, and also flexible and scalable, fine grained access control must be keep in the cloud systems. Attribute based encryption (ABE), allows for rare access control on encrypted data. In its key policy extract, the primitive enables senders to encrypt messages under a set of attributes and private keys are associated with access structures that specify which cipher texts the key holder will be allowed to decrypt .we propose the Hierarchical Attribute Set Based Encryption (HASBE) to develop a new security feature for various organizational platforms. It is implemented using cipher text policy by encrypting and decrypting the data in the cloud so that the cloud system becomes more scalable and flexible by enforcing data owners to share their data with data consumers controlled by the domain authority.
