A Method of Declassifiers Placement in Information Flow Analysis

Abstract

In this paper, we propose a method to produce suggestions of declassifiers placement for correcting type errors in information flow analysis. Though the declassification is a useful method to resolve illegal information flow, it can be a difficult and time-consuming task to manually place declassifiers. By our method, developers only need to select a declassifiers placement from suggestions for correcting errors. We proved that produced suggestions can resolve type errors and at least one suggestion can be produced, and implemented our proposed method as a prototype tool.
