Tool support for Confidentiality by Construction
In many software applications, it is necessary to preserve confidentiality of information. Therefore, security mechanisms are needed to enforce that secret information does not leak to unauthorized users. However, most language-based techniques to enable information flow control work post-hoc, deciding whether a specific program violates a confidentiality policy. In contrast, we have proposed a refinement-based approach to derive programs that preserve confidentiality-by-construction in previous work. This approach follows the principles of Dijkstra’s correctness-by-construction. In this extended abstract, we present the implementation and tool support of that refinement-based approach allowing to specify the information flow policies first and to create programs which comply to these policies by construction. In particular, we present the idea of confidentiality-by-construction using an example and discuss the IDE we have developed.
