Passive Query-Recovery Attack Against Secure Conjunctive Keyword Search Schemesen if trusted, data breaches are ubiquitous. To prevent information leakage one can store documents encrypted. If encrypted under traditional schemes, one loses the ability to perform simple operations over the documents, such as searching through them.
