Security in integrated vetronics: Applying elliptic curve digital signature algorithm to a safety-critical network protocol-TTP/C

Military vetronics consists of a variety of sub-systems which perform a myriad of functions. These sub-systems are connected together using gateways and backbone networks to provide the crew, the military and decision makers with real-time data, enabling information sharing. This integration of the vetronics architecture provides greater functionalities than an individual sub-system. However, this poses a potential risk from malicious attacks. For example, an attack on a safety-critical Drive-by-wire sub-system can affect the safety of the crew and compromise the mission. In this paper, we explore and carry out a feasibility study of applying elliptic curve digital signature algorithm on a safety-critical time-triggered protocol (TTP/C) to provide node authentication and message integrity.
