摘要
With the rapid development of cloud computing, more and more data owners are motivated to outsource their data to cloud for various benefits. Due to serious privacy concerns, sensitive data should be encrypted before being outsourced to the cloud. However, this results that effective data utilization becomes a very challenging task, such as keyword search over ciphertexts. Although many searchable encryption methods have been proposed, they only support exact keyword search. In our paper, we propose a method which could support both the fuzzy keyword search and access control over ciphertexts. Our proposed method achieves fuzzy keyword search and access control through algorithm design and Ciphertext-Policy Attribute-based Encryption. We present word pattern which can be used to balance the search efficiency and privacy. The experimental results demonstrate the efficiency of our method.
