Safe and secure software updates on high-performance mixed-criticality systems: The UP2DATE approach


Over-The-Air Software Updates (OTASU) are gaining popularity on the safety-critical domain. The motivation behind this trend is twofold. On the one hand, the ability of adding new functionality and services to the system without a complete redesign makes product makers more competitive and improves user experience. On the other hand, the increasing connectivity of emerging embedded devices makes OTASU a crucial cyber-security demand to keep the system up-to-date with latest security patches. However, the application of OTASU in the safety-critical domain is not straightforward, as they are not contemplated by current functional safety standards. The UP2DATE European H2020 project, seeks to provide solutions to cope with the challenging requirements of safety and security standards with respect to software updates. This paper gives an overview of UP2DATE, its foundations and the initial description of its safe and secure architecture that builds around composability and modularity on heterogeneous high-performance platforms.
