Information Security Analysis and Implementation Methods for Industrial Wireless Transmitters

从工业无线通信技术特点来看,大多数无线网络是开放性的,采用明文传输,不仅不符合路由安全管理要求和权限管理规范,而且抗电磁干扰能力和容错能力也不足。结合目前工业现场无线变送器使用情况和现场用户关切,分析了典型测控系统的安全需求,强调了无线变送器信息安全的必要性,提出了提高数据安全的若干方法及应用场景的防爆安全性建议,旨在多角度地保证无线变送器的网络安全、电磁环境安全和应用环境安全。

From the perspective of the characteristics of industrial wireless communication technology,most wireless networks are open and adopt plaintext transmission,which not only does not comply with routing security management requirements and permission management standards,but also lacks electromagnetic interference resistance and fault tolerance capabilities.Based on the current usage of wireless transmitters in industrial sites and the concerns of on-site users,this paper analyzes the security requirements of typical measurement and control systems,emphasizes the necessity of information security for wireless transmitters,and proposes several methods to improve data security and explosion-proof safety suggestions for application scenarios.The aim is to ensure the network security,electromagnetic environment security,and application environment security of wireless transmitters from multiple perspectives.
