ABEKS:ATTRIBUTE-BASED ENCRYPTION WITH KEYWORD SEARCH
With the growing quantity of information and data,cloud computing technology is an effective way to solve the problems of data storage and management.To ensure the sensitive information stored in the cloud security,data should be encrypted before outsourcing,which makes data utilization become a big challenge.Although traditional searchable encryption scheme provide some approaches to search over the encrypted data by keyword,they cannot support flexible access control policies.In this paper,we propose the Attribute-Based Encryption with Keyword Search (ABEKS) architecture in which data owner can configure an access policy table to make the specific users can search with specific keywords.We construct a searchable encryption scheme based on ABEKS,in which data owner encrypts the keyword with a predefined attribute policy table,so that it can be searched where the data users attribute set satisfies the access policy.To the best of out knowledge,we first combine ABE and searchable encryption to achieve access controlled keyword search.It greatly improves the flexibility of search able encryption.Moreover,ABEKS architecture is offered for cloud computing scenario.Our scheme is effective and efficient which secure against outer and inner attacks.
