Information hiding for trusted system design
For a computing system to be trusted, it is equally important to verify that the system performs no more and no less functionalities than desired. Traditional testing and verification methods are developed to validate whether the system meets all the requirements. They cannot detect the existence or show the nonexistence of the unknown undesired functionalities. In this paper, we propose a novel approach that converts this problem to a less challenging design quality measuring problem. Our approach is based on information hiding and constraint manipulation of the original system design specification. We lay out the basic requirements for our approach and demonstrate it through the popular graph coloring problem. Results show that information can be embedded into the original graph without significant impact to the solution quality. However, when the same information is added to the graph modified based on our approach, there will be noticeable drop in the solution quality. Categories ...
