Abstract
A method for confidentially querying an encrypted database hosted by a server. The user transmits, to the server, a request including a predicate. The predicate is evaluated in an encrypted manner on different records of the database. The records that satisfy the query are transferred blindly into a container. The container is transmitted to the user who decrypts the content of same. If the container is full, the user sends a continuation request to the server. If this is not the case, the records of the successive containers that have already been decrypted form the response to the request.
