Integrated vetronics survivability: Architectural design and framework study for vetronics survivability strategies

Network enabled capabilities (NEC) and electronic architectures inmodern-daymilitary vehicles fundamentallychange the way in which the military conduct its operations. In-vehicle electronic (vetronics) architecturesconsist of the integration of a variety of safety-critical, deterministic and non-deterministic sub-systems throughgateways and backbone networks. This assimilation provides the military with the required informationsuperiority, battle space information integration and new capabilities. However, with this integration comesadded security and safety risk. In essence, different communication nodes within the vehicle could be accessedwith malicious intentions through NEC or by allowing tampered nodes to be part of the system duringreconfiguration. Attacks on safety-critical sub-systems can affect the safety of the crew and also the completionof themilitary mission. This paper presents a novel integrated vetronics survivability architecture framework toprotect and recover vehicle's vetronics from the growing threats of attacks. Architecture components areidentified, and their behaviour is analysed to present an innovative vetronics survivability architecturalframework.
