An inference attack is a malicious way to obtain the result of an unauthorized query
by combining the database schema, the results of the authorized queries and the code
(meaning) of the queries.
A database instance is $k$-secret if an attacker cannot narrow down the candidates
of the results of the unauthorized query to less than $k$.
We already proposed a method of deciding a sufficient condition of $k$-secrecy
by reducing the problem to a model counting problem for the propositional logic.
This paper proposes an improvement of our previous verification method by incorporating the information on a schema and queries to reduce the size of a generated formula.
We show the effectiveness of the proposed optimization based on the experimental results obtained by our verification tool. |
