Abstract: This Research Paper investigates how Predicate Based Encryption (PBE) could be leveraged within the Cloud to protect data. PBE is a novel family of asymmetric encryption schemes in which decryption of a cipher-text is dependent upon a set of attributes satisfying a certain predicate, allowing for selective ne-grained access control to be specied over cipher-texts. It is argued that obfuscation of one's data is not enough when seeking to protect data. The control of how one's data is used and the trust a orded to service providers is equally as important. To this end, three archetypal scenarios are described that illustrate ways in which service users could specify precisely with whom they wish to share their data, for what purpose, and for how long. Furthermore, two additional scenarios are presented that would allow a service provider to facilitate keyword search over encrypted data using expressive queries supporting conjunction and disjunction of terms.
Keywords: PBE, encryption, decryption, conjunction, disjunction.
