Vetronics in modern day military vehicles have evolved to include network enabled capability (NEC) allowing the use of electronics architectures to integrate different sub-systems. Integrated vehicle electronics (vetronics) offer improved performance, efficiency and new capabilities at the subsystem, system and system-of-systems level. However, this integration is associated with magnified risk and compromise from cyber attacks. Potential cyber attacks could be from an external source where a node is accessed by a malicious intruder using NEC, or internal to the vehicle such as a passive attack waiting to be triggered by an event. This paper provides an understanding of applying survivable systems principles of preventive and reactive mechanisms to the to mitigate internal and external threats. Requirements are derived and a novel top level architecture for vetronics survivability is presented.
Today's military platforms are equipped with variety of sensors and effectors. However, these components are rarely interconnected or are only linked via manufacturer-specific, proprietary interfaces. This hinders changes to and extensions of platform components. Often platform modifications are only possible with the help of the original integrator, which complicates a seamless integration of new components. In order to unify the interfaces of sub-systems and enhance platform interoperability, several open architecture initiatives have been launched on national and multi-national levels. Some as the NATO Generic Vehicle Architecture (NGVA) have already recognised that new approaches for system verification and acceptance need to be considered. Nevertheless, these considerations are still on the conceptual level and no tools for rigorous interface conformity testing are yet in place. This paper describes a concept supporting the testing of interface specifications in early standardisation phases as well as the verification of platform architecture implementations in actual systems later on. On the example of the NGVA, a test framework is presented focussing on the reuse of test artefacts from early specification checking for later conformance and final acceptance testing. The approach is validated by means of a case study supporting the NGVA standardisation
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
