SO-ITS: a secure offloading schemefor intelligent transportation systems in federated fog-cloud

Intelligent driving technologies have significantly reduced traffic congestion and road accidents, enhancing overall safety by enabling vehicles to communicate with their surroundings, thus keeping drivers informed of traffic conditions and critical events. Adequate data security demands mutual authentication for secure exchanges and robust offloading procedures to guard against potential attacks. This paper presents the SO-ITS scheme, tailored for safe data offloading in intelligent driving systems. The scheme’s robustness is validated using the AVISPA tool, confirming its resilience to known threats. Comparative analysis with existing schemes assesses communication overhead, computational cost, and bit complexity. At the same time, performance is evaluated through NS-3 simulations, measuring PDR, throughput, and EDD across various scenarios. Results demonstrate that the SO-ITS scheme provides strong security, low communication overhead, and moderate computational complexity, establishing it as a promising solution for secure intelligent transportation systems.
