Abstract:
Cloud storage is a major remote data management service, but encryption is the best way to prevent data disclosure. Since clients can search encrypted data files, public key encryption with keyword search (PKSE) is promising.
The cloud server queries encrypted data files using a search token generated by a client. When PKSE meets cloud, a serious attack arises. The cloud server can use search tokens to learn about a newly added encrypted data file containing the keyword previously queried and its privacy information.
We propose a forward secure public key searchable encryption scheme that prevents cloud servers from learning about newly added encrypted data files containing the keyword queried. We present a framework for attribute-based forward secure public key searchable encryption schemes to better understand the design principle. Finally, our method works.
