Research on the security mechanism for interconnection between PROFIBUS and Internet

Abstract

The connection between PROFIBUS network and Internet can realize remote real-time monitoring device on the fieldbus. This paper conducts detailed analysis and research advance on network security based on the interconnection methods between PROFIBUS and Internet, and proposes a PROFIBUS industrial network security model. An embedded gateway is developed especially for meeting the security requirement in this research work. With compact structure and low cost, it paves the way to realize real-time monitoring PROFIBUS device safely via Internet.

1 Introduction

PROFIBUS is the most popular fieldbus in manufacturing, process control and automation at present. How to make the fieldbus network access to Internet and enable the enterprise’s information network and control network interconnect has become a research hotspot of industrial network technology.

The industrial network is different from other commercial networks due to its service environment and purpose. Generally, the industrial network in enterprise is structured by two parts, information network and control network. The information network is used to enterprise management. The control network connects the production devices and equipments together and makes the production process control and monitor centralized. In this research, the control network is based on PROFIBUS. As an independent unit, the business information confidentiality and preventing hacker invasion is crucial to the enterprise internal network. To realize remote control and management to production process, status and parameters of production equipment should be real-time provided. In other words, the control system based on PROFIBUS should be accessed via the industrial network and Internet. Therefore, reliable and effective security method should be taken when the network interconnect. Currently there is no unified solution to solve the network security problems when embedded gateway is used to connect to Internet. Because of the limited embedded resources, the existing security policy for PC could not be put to use directly. It is necessary to design a compact security strategy according to the practical application scenario for PROFIBUS. In this researchˈa method based on embedded Web gateway is proposed to realize the interconnection between PROFIBUS-DP network and Internet and some compact security methods are proposed to provide security assurance when user access to the PROFIBUS device via Internet.
