Nowadays, autonomous vehicles are incorporated into farms to facilitate manual labour. Being connected vehicles, as IoT systems, they are susceptible to cyber security attacks that try to cause damage to hardware, software or even living beings. Therefore, it is important to provide sufficient security mechanisms to protect both the communications and the data, mitigating any possible risk or harm to farmers, livestock or crops. Technology providers are aware of the importance of ensuring security, and more and more secure solutions can be found on the market today. However, generally, these particular solutions are not sufficient when they are part of complex hybrid systems, since there is no single global solution proposal. In addition, as the number of technologies and protocols used increases, the number of security threats also increases. This article presents a cyber-security architecture proposal for swarms of heterogeneous vehicles in smart farming, which covers all of the aspects recommended by the ISO 7798-2 specification in terms of security. As a result of this analysis, a detailed summary of the possible solutions and available technologies for each of the communication channels of the target system as well as some recommendations are presented.

智能农业中无人驾驶车辆群的安全架构

如今，无人驾驶汽车已纳入农场，以促进体力劳动。作为物联网系统的互联车辆，它们容易受到网络安全攻击的攻击，这些攻击试图损坏硬件，软件甚至生物。因此，重要的是要提供足够的安全机制来保护通信和数据，从而减轻对农民，牲畜或农作物的任何可能的风险或损害。技术提供商意识到确保安全性的重要性，并且当今市场上可以找到越来越多的安全解决方案。但是，通常，当这些特定解决方案是复杂的混合系统的一部分时，它们是不够的，因为没有单一的全局解决方案建议。另外，随着使用的技术和协议的数量增加，安全威胁的数量也增加。本文提出了针对智能农业中的异构车辆群的网络安全体系结构提案，该提案涵盖了ISO 7798-2规范在安全性方面建议的所有方面。分析的结果是，针对目标系统的每个通信通道，提供了可能的解决方案和可用技术的详细摘要以及一些建议。
