IHOP: Improved Statistical Query Recovery against Searchable Symmetric Encryption through Quadratic Optimization [article]

Simon Oya, Florian Kerschbaum
2021 arXiv   pre-print
In this work we present IHOP, a statistical-based query recovery attack that formulates query recovery as a quadratic optimization problem and reaches a solution by iterating over linear assignment problems  ...  Searchable Symmetric Encryption (SSE) schemes allow a client to perform secure searches over encrypted databases on a remote server.  ...  Quadratic Query Recovery with IHOP In this section, we present our query recovery attack, which we call IHOP (Iteration Heuristic for quadratic Optimization Problems).  ...
