The prototype of the industrial firewall has been tested in multiple stages in Xinmi Ganghua. The functions include firewall management, IP/MAC filtering, Modbus self-learning and deep parsing, ACL management, one-click addition of whitelist alarms, Modbus range control, security domain addition, session table query, aging time configuration, security domain data flow control, attack defense, firewall running logs, and event statistics analysis. The test results show that the product can effectively reduce the power consumption and improve the packet processing efficiency compared with the product in the traditional architecture. At the same time, on the basis of realizing the requirements of low delay and high throughput, the hardware can also use the fanless closed design to ensure that the product can be deployed in a variety of industrial and energy application scenarios with complex environments.
The success of the industrial firewall prototype test not only proves the feasibility of high-performance RISC-V chip application in industrial firewall, but also lays a solid foundation for the wide application of the subsequent RISC-V open source chip architecture in industrial control, edge computing, smart energy, smart home and other scenarios.

With its rich experience in the field of industrial control safety and strong technical strength, Winut has effectively boosted the successful completion of the “China Core” industrial firewall from product design, research and development to testing. The deep packet parsing engine independently developed by Winut can detect more than 100 industrial protocols, which can realize real-time analysis and accurate identification of industrial control protocol characteristics. Long Guodong, chairman and CEO of Winut, said that the development of industrial control security products equipped with Saifang RISC-V chip platform is a specific practice that actively responds to the overall policy and strategy of national network security, and is also a joint innovation of basic hardware and application software. The landing in Ganghua Group is of representative significance, and Winut will continue to increase investment and do a good job in the field of critical information infrastructure.

“As an energy company with a history of 160 years, safety has always been a top priority for the Group’s business development. As the key infrastructure for the nation’s energy, ensuring data and cybersecurity is not only the foundation for us to provide high-quality services to our customers, but also the key to driving service innovation and accelerating the transition to smart energy.” Xi Dan, vice president of Ganghua Smart Energy, said that the Group and Saifang Technology and Winut, two excellent industry partners, are hoping to start from the bottom of the chip research and development, the initiative for security in their own hands, at the same time, RISC-V chip itself open source, open, customizable and other characteristics, can also make the product can be tailored to the needs of different industries and customers. To achieve a more flexible combination of functional modules and strong adaptability, it is equivalent to installing “double insurance” for energy security services, which has unique advantages in safety, efficiency and comprehensive cost.

The industrial firewall product jointly developed by the three parties is the Fang · Zhihong 7000 series high-performance RISC-V chip developed by Saifang Technology. The chip is equipped with a high-performance 64-bit multi-core RISC-V CPU, with powerful multimedia processing capabilities, equipped with a variety of peripheral interfaces: PCIe, GMAC, eMMC, USB, MIPI, HDMI, etc., supports a variety of encryption engines, and can be set according to application scenarios and performance requirements to achieve the best performance/power balance. Fang · Jinghong 7000 series RISC-V chips can meet the real-time processing needs of various edge ends, and play a good benchmarking effect for RISC-V to open up intelligent energy and other industrial application scenarios.

“Many people’s impression of RISC-V is still in low-end applications, but it is not. RISC-V has the characteristics of simplification, openness and customization. Using this instruction set architecture to design the chip, it can flexibly combine and expand multiple functional modules to meet the needs of different customers’ middle and high-end applications. At the same time, RISC-V chips have better performance in terms of energy efficiency and overall cost.” Saifang technology CEO Xu Tao said.

Industry experts speak highly of the achievements made by the three parties in the field of industrial firewalls, and this cross-field deep technical cooperation has strong promotion significance. For the energy industry, the world’s first industrial firewall equipped with RISC-V chips passed the test in a specific scenario, which is a phased breakthrough in the use of autonomous controllable products in the field of critical information infrastructure; For the chip industry, the application of Saifang SoC chip in the industrial firewall will promote the development of RISC-V in China into the fast lane; For the industrial control industry, the use of self-developed chips in products has opened up a new path for the safety upgrade and efficiency improvement of domestic industrial control.

With the actual testing of the industrial firewall prototype, the three parties will jointly promote the localization process of smart energy solutions in key technologies in the future, escort high-quality urban gas services with a stronger information security moat, and apply RISC-V chips to more scenarios, while building a solid national information security base, but also help speed up the innovation of smart energy.
