This paper has proposed a quantitative analysis method based on security entropy to work out the problem of quantitative analysis in classificatory information systems. Firstly, the security theorems of classificatory information systems have been defined, the uncertainty for the system's determinations on the irregular access behaviors by means of the(More)
1 Abstract—In this paper, we propose analysis methods based on security entropy to overcome the problem of quantitative analysis, after going through the study of access control capability assessment for computer information system. At First, we computed the uncertainty how system determine irregular access behavior using the security entropy theory. Next,(More)
