However, with the advancement of comprehensive energy services under ubiquitous power physical networks, data sharing between internal departments of enterprises and between enterprises becomes a key problem for restricting the development of comprehensive energy services. Because the comprehensive energy metering data has the characteristics of confidentiality, safety, real-time performance, privacy, incapability of being modified and the like, the sharing of the comprehensive energy metering data is an important bottleneck for the floor development of the current comprehensive energy service. The metering data not only needs to be shared with high efficiency among enterprises, but also is indispensable among various energy suppliers, and the potential value of the metering data can be better exerted only by breaking the data sharing barriers among different types of energy suppliers.
The current method for sharing the electric power metering data mainly comprises the steps that an applicant submits an electric power data access request to a data center, and after the applicant waits for approval to pass, the applicant can obtain original electric power data from the data center. In the data sharing mode, a network firewall is often arranged between an intranet and an extranet to ensure the information security of enterprises. Meanwhile, in order to ensure the privacy of the electric power metering information, the applicant shields the data by the data center according to the data sharing requirement before obtaining the original data. In addition, there is a data sharing method, mainly, the electric power data is deployed into a preset container, an IP number and a port number are allocated to the preset container, the user directly accesses the preset container through the IP number and the port number, and according to a corresponding sharing request, the original electric power data is processed, so that the user can only obtain the processed data.
The data sharing process is complicated, a large amount of time is consumed, and the real-time requirement on the data is difficult to meet. In the data sharing process, the original data in the process cannot be guaranteed not to be changed and leaked. Although a firewall is arranged between the intranet and the extranet, the security of data transmission still cannot be ensured absolutely, and the risk of being attacked exists. The second sharing scheme reduces part of programs, shortens data sharing time, and ensures data safety and privacy to a certain extent through processing and processing the data. However, there is still a risk of being altered during the data sharing process.
