Summary:As more and more data is outsourced to cloud which is assumed to be a semi-trusted server, it is necessary to encrypt the sensitive data stored in the cloud. However, it brings a series of problems, such as: How to search over the encrypted data efficiently and securely? How should a data owner grant search capabilities to the data users? To solve these problems, we propose two attribute-based keyword search and data access control schemes based on public-key searchable encryption and attribute based encryption. Our solutions allow a data owner to control the access policy and grant the search policy to any data user who wants to retrieve the encrypted data efficiently.
