| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | 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 $k$. This paper proposes a method of deciding a sufficient condition of $k$-secrecy by reducing the problem to a model counting problem for the propositional logic. The paper shows the experimental results conducted on the verification tool based on the proposed method. Furthermore, we provide an upper-bound of the size of a candidate database instance so that our sufficient condition of $k$-secrecy becomes a necessary condition. |
