This repository contains the implementation of Aura, a non-interactive dynamic searchable symmetric encryption (DSSE) scheme. This is the first DSSE scheme that achieves forward and Type-II backward privacy [1] while supporting non-interactive queries. The detailed construction and security proof are presented in our NDSS'21 paper [2].

makeAfter compiling the project, three executable files of Aura will be generated. The first one is SSETest, which runs Aura client and server operations as a local procedure. This can be used to evaluate the performance of Aura with no communication cost. The other two files (AuraServer and AuraClient) can be used to execute Aura in a networked environment. Particularly, the AuraServer starts an Apache Thrift server which can process the setup, update, query operations from the AuraClient. The results from these two executable file reflect the performance of Aura in real-world networks.
All the above executable files can be executed without extra parameters.
