A formal contract distinguishes between assumptions, which are constraints that the designer of a component puts on the environments in which the component can be used safely, and guarantees, which are promises that the designer asks from the team that implements the component. A theory of formal contracts can be formalized as an interface theory, which supports the composition and refinement of both assumptions and guarantees. Although there is a rich landscape of contract-based design methods that address functional and extra-functional properties, we present the first interface theory designed to ensure system-wide security properties. Our framework provides a refinement relation and a composition operation that support both incremental design and independent implementability. We develop our theory for both stateless and stateful interfaces. Additionally, we introduce information-flow contracts where assumptions and guarantees are sets of flow relations. We use these contracts to illustrate how to enrich information-flow interfaces with a semantic view. We illustrate the applicability of our framework with two examples inspired by the automotive domain.","lang":"eng"}],"year":"2024","publication_identifier":{"issn":["0925-9856"],"eissn":["1572-8102"]},"publisher":"Springer Nature","ec_funded":1,"article_type":"original","status":"public","oa_version":"Published Version","department":[{"_id":"ToHe"}],"date_published":"2024-05-23T00:00:00Z","day":"23","publication_status":"epub_ahead","publication":"Formal Methods in System Design","external_id":{"arxiv":["2002.06465"]},"project":[{"grant_number":"101020093","call_identifier":"H2020","_id":"62781420-2b32-11ec-9570-8d9b63373d4d","name":"Vigilant Algorithmic Monitoring of Software"},{"grant_number":"F8502","_id":"34a1b658-11ca-11ed-8bc3-c75229f0241e","name":"Interface Theory for Security and Privacy"}],"author":[{"last_name":"Bartocci","full_name":"Bartocci, Ezio","first_name":"Ezio"},{"full_name":"Ferrere, Thomas","last_name":"Ferrere","orcid":"0000-0001-5199-3143","id":"40960E6E-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas"},{"id":"40876CD8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2985-7724","last_name":"Henzinger","full_name":"Henzinger, Thomas A","first_name":"Thomas A"},{"first_name":"Dejan","id":"41BCEE5C-F248-11E8-B48F-1D18A9856A87","last_name":"Nickovic","full_name":"Nickovic, Dejan"},{"last_name":"Oliveira da Costa","full_name":"Oliveira da Costa, Ana","orcid":"0000-0002-8741-5799","id":"f347ec37-6676-11ee-b395-a888cb7b4fb4","first_name":"Ana"}],"doi":"10.1007/s10703-024-00447-0","_id":"17094","oa":1,"main_file_link":[{"url":"https://doi.org/10.1007/s10703-024-00447-0","open_access":"1"}],"related_material":{"record":[{"status":"public","id":"11355","relation":"shorter_version"}]},"language":[{"iso":"eng"}],"quality_controlled":"1","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87"}
