{"abstract":[{"lang":"eng","text":"Information flow analysis investigates the flow of data in applications, checking in particular for flows from private sources to public sinks. Flow- and path-sensitive analyses are, however, often too costly to be performed every time a security-critical application is run. In this paper, we propose a variant of proof carrying code for information flow security. To this end, we develop information flow (IF) certificates which get attached to programs as well as a method for IF certificate validation. We prove soundness of our technique, i.e., show it to be tamper-free. The technique is implemented within the program analysis tool CPAchecker. Our experiments confirm that the use of certificates pays off for costly analysis runs."}],"doi":"10.1007/978-3-030-02508-3_23","project":[{"_id":"1","name":"SFB 901"},{"_id":"3","name":"SFB 901 - Project Area B"},{"name":"SFB 901 - Subproject B4","_id":"12"}],"language":[{"iso":"eng"}],"date_updated":"2022-01-06T07:02:40Z","file":[{"file_id":"5837","relation":"main_file","file_size":518016,"creator":"mtoews","access_level":"closed","content_type":"application/pdf","date_created":"2018-11-26T15:11:32Z","file_name":"Töws-Wehrheim2018_Chapter_InformationFlowCertificates.pdf","date_updated":"2018-11-26T15:11:32Z","success":1}],"department":[{"_id":"77"}],"file_date_updated":"2018-11-26T15:11:32Z","status":"public","citation":{"ieee":"M.
