As rapid development and deployment of Internet technology, numerous data have been overwhelmed. To our best knowledge, efficient data retrieval schemes of ciphertext were not yet extensively studied. Most of studies focus on the complete security of their proposed scheme, and vast amounts of expensive operations are concentrated to the entity which performs searching process. In this paper, we describe an efficient way to provide searching of ciphertext while achieving the security properties. It provides also comparable storage overhead to existing approaches as well as providing fine-grained access control and one-to-many distribution property by taking advantage of attribute-based encryption.
