The theme of the speech is discussed and interpreted from various aspects such as chip, network, data and application layer.

Jiang Zhaohui, founder and CEO & CTO of Guangdong Yuefang Technology Co., LTD., shared his views from the perspective of chips. The application status of industrial chips in China is that the industrial scene is extremely fragmented, the chip specification needs are complex, and the power consumption, area and cost are highly sensitive. Under the traditional chip development method, customized development for industrial segmentation scenarios, and huge investment in the development time and cost of streaming chips, so China's industrial chip market has been ruled by foreign manufacturers for many years, and domestic manufacturers mostly start from the consumer level, there is still a large catch-up space. Therefore, how to quickly and efficiently develop domestic independent controllable industrial chips is the key to China's new digital infrastructure, at the same time, Jiang Zhaohui shared that by creating an industrial chip DSA platform based on RISC-V open source instruction set architecture, and then superposing the software stack ability, you can solve the above problem and achieve domestic independent controllable industrial chips. This technology can be applied to industrial and consumer iot scenarios, and can be expanded to intelligent industrial perception and other fields, effectively helping Guangdong and Macao technology enterprises to enhance their digital capabilities.

Yang Tianshi, chief security expert of Beijing Qiming Star Information Security Technology Co., LTD., mentioned that the computing network is a new type of information infrastructure with computing as the center and the network as the foundation, and the network, cloud, data, intelligence, security, edge, end, and chain (ABCDNETS) are deeply integrated, and the goal of "ubiquitous computing power, co-existence of computing network, intelligent arrangement, and integrated service" is realized. Gradually promote computing power to become the same as water and electricity, can be "one-point access, access and use" of social services, to achieve the vision of "computing power everywhere, network everywhere, intelligence everywhere". By building an integrated and collaborative security guarantee system, data risk identification is carried out using technical detection means, security protection of cloud applications, and safe and reliable computing power to cope with advanced threat attacks. Yang Tianshi stated that by setting up the infrastructure layer (1 cloud security base), the capability arrangement layer (1 security center, 1 data center), and the operation service layer (1 security operation center) to build the security architecture of the computing power center, it can effectively help ensure the security of the communication network.

At the same time, Wang Wenyong, distinguished professor of the School of Computer Science and Engineering, Macao University of Science and Technology, also shared that cross-border data circulation is the cornerstone of the exchange of global social and economic activities, and the G20 digital economy track in 2022 listed "free flow of trusted data and cross-border data flow" as one of the three core topics, and cross-border trusted data space is the extension and adaptation in cross-border scenarios. It is a distributed infrastructure built on the existing information network with security gateway as the boundary and its network space. Based on the concept of traceability, accountability and multi-party compliance, it ensures the compliance and performance of data flow agreements through basic framework and systematic technical arrangements, and solves the security and trust problems among different entities such as providers, users and service providers of data elements in different territories. Support the establishment of a trusted data ecosystem to achieve reliable, controllable, compliant and co-governed data sharing, exchange and application. Data elements are the foundation of digitalization, networking and intelligence, and trusted data space mainly promotes the release of value of data elements through the construction of a digital economy with data as the key element. Wang Wenyong also shared the current cooperation between Macao University of Science and Technology and Guanglian Century to jointly create a demonstration application of cross-border trusted data space based on SD-WAN, which helps to promote the construction of Guangdong-Hong Kong-Macao Greater Bay Area and Hengqin Guangdong-Macao Deep Cooperation Zone.

At the same time, Tao Yaodong, director of the Industrial Internet Security Research Center of Beijing Jiaotong University, also said that the trusted data circulation is the key to promote the interconnection of industrial data value, and the trusted data space is a distributed key data infrastructure for sharing, circulation and application on the existing information network, and ensures the confirmation, implementation and maintenance of the data circulation agreement through systematic technical arrangements. Solve security and trust issues among data element providers, users, and service providers to achieve data-driven digital transformation. Trusted data space system architecture needs to be constructed from the business perspective, functional perspective, process perspective and technical perspective. First, the business perspective describes the three main participants of trusted data space: data providers, data users and intermediate service providers; Functional perspective describes three core components and nine main functions of trusted data space business activities; From the perspective of process, the author describes the activity process of each participant in the trusted data space from the eight life cycles of data circulation. The technical perspective describes the eight main functions of trusted data space and the key technologies needed; Enable data exchanges and industrial Internet platforms by deploying flexible solutions, building spatial architectures for multi-party business needs to serve local applications in the industry.
