Additionally, the thesis analyzes solutions to perform I/O operations securely. For this, hardware requirements are formulated and applied in a hardware audit on a special I/O accelerator. Last, this thesis focuses on methods to gain assurances for correct implementation. First, the Decentralized Label Model is applied to the C language and connected to MILS properties. Second, this thesis discusses compositional certifications in the Common Criteria and proposes a new certification strategy that matches with MILS.}, keywords = {Security, MILS, High-Assurance, Embedded Systems}, note = {}, url = {https://mediatum.ub.tum.de/1344365}, }
