Secure and Efficient Data Retrieval Using Attribute-Based Encryption in Distributed System
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 3
Abstract
Attribute-based encryption (ABE) is a public-key based one-to-many encryption that allows users to encrypt and decrypt data based on user attributes. A promising application of ABE is flexible access control of encrypted data stored in the distributed system, using access polices and ascribed attributes associated with private keys and cipher text. One of the main efficiency drawbacks of the existing ABE schemes is that decryption involves expensive pairing operations and the number of such operations grows with the complexity of the access policy. To overcome this drawback we have proposed a method in which we will provide rich expressiveness of index terms by exploiting ABE, thus providing data security. The data will be stored in the form of trie structure, which will reduce the search complexity and will support one upload many download feature because of use of attribute based encryption.
