Dynamic Searchable Symmetric Encryption with Minimal Leakage and Efficient Updates on Commodity Hardware

Attila A. Yavuz and Jorge Guajardo


Dynamic Searchable Symmetric Encryption (DSSE) enables a client to perform keyword queries and update operations on the encrypted file collections. DSSE has several important applications such as privacy-preserving data outsourcing for computing clouds. In this paper, we developed a new DSSE scheme that achieves the highest privacy among all compared alternatives with low information leakage, non-interactive and efficient updates, compact client storage, low server storage for large file-keyword pairs with an easy design and implementation. Our scheme achieves these desirable properties with a very simple data structure (i.e., a bit matrix supported with two static hash tables) that enables efficient yet secure search/update operations on it. We prove that our scheme is secure (in random oracle model) and demonstrated that it is practical with large number of file-keyword pairs even with an implementation on simple hardware configurations.

Note: Some minor changes on the writing (especially related work) and edit on the Table 1 values.
