The Internet of Vehicles (IoV) plays a crucial role in advancing intelligent transportation systems. However, due to limited processing power, IoV faces challenges in independently handling large volumes of data, necessitating the use of offloading as a solution. Offloading data in wireless environments raises security concerns, highlighting the need for robust data protection mechanisms. This study introduces a secure offloading (SO) scheme within the Fog-Cloud Federation for IoV. The proposed NSO-VFC scheme undergoes both informal and formal analysis using the Avispa tool, demonstrating resilience against active and passive attacks. Performance evaluations indicate that the security measures of NSO-VFC meet acceptable standards compared to similar approaches. Nonetheless, the heightened focus on security incurs higher computational and communication costs than alternative strategies. Simulation experiments using the NS3 tool involve varying numbers of IoVs (50, 70, and 100), revealing that increased IoV density correlates with enhanced packet delivery rates and throughput within the NSO-VFC scheme.
车联网（IoV）在推进智能交通系统方面发挥着关键作用。然而，由于处理能力有限，车联网在独立处理大量数据时面临挑战，因此需要采用卸载作为解决方案。在无线环境中卸载数据引发了安全问题，凸显了强大的数据保护机制的必要性。本研究在车联网的雾-云联盟中引入了一种安全卸载（SO）方案。所提出的NSO-VFC方案使用Avispa工具进行了非正式和形式化分析，证明了其对主动和被动攻击的抵御能力。性能评估表明，与类似方法相比，NSO-VFC的安全措施符合可接受标准。尽管如此，对安全性的高度关注比其他策略带来了更高的计算和通信成本。使用NS3工具进行的模拟实验涉及不同数量的车联网设备（50、70和100），结果表明，在NSO-VFC方案中，车联网密度的增加与数据包交付率和吞吐量的提高相关。
