碩士 === 淡江大學 === 資訊工程學系碩士班 === 106 === Information technology (IT) is one of the most important factors in production systems and automation innovation in industry. In Germany, the term "Industry 4.0" summarizes the various activities and developments of industrial processes such as production, logistics and automation. Many research and development projects work in different aspects. From the point of view of enterprises related to the industrial and information technology industries, information security in the information technology industry is considered to be an important part of smart manufacturing. Although many current IT security solutions can be applied in Industry 4.0, the entire system required in Industry 4.0 needs to be integrated with the Internet of Things, with the added functionality of intelligence and combined with the analysis of big data to provide the most Jiahua''s production process considers many factors such as its functionality, immediacy, stability, energy saving, and security. Security is still not integrated in many of the current industry 4.0 equipment, but it has a profound impact on the overall plant production progress and stability, so it is extremely necessary to complete the application of Industry 4.0 on the basic security mechanism and security architecture. This paper proposes a lightweight method of industrial data encryption transmission and device authentication, using the WG-8 encryption algorithm and improving its tailing randomness to protect the plant''s communication transmission. In order to comply with the actual plant equipment, we used the Raspberry Pi3 B+ as an experimental test machine in the experiment, and designed and implemented our proposed communication security encryption algorithm. The experimental results prove that the WG-8 encryption algorithm, which will allow Raspberry Pi3 central processing unit (CPU) usage increased by 40%, but it provides industrial Internet of Things more secure communication methods and device certification.
