Research on Data Tampering Prevention Method for ATC Network Based on Zero Trust

The traditional air traffic control information sharing data has weak security characteristics of personal privacy data and poor effect, which is easy to leads to the problem that the data is usurped. Starting from the application of the ATC (automatic train control) network, this paper focuses on the zero trust and zero trust access strategy and the tamper-proof method of information-sharing network data. Through the improvement of ATC’s zero trust physical layer authentication and network data distributed feature differentiation calculation, this paper reconstructs the personal privacy scope authentication structure and designs a tamper-proof method of ATC’s information sharing on the Internet. From the single management authority to the unified management of data units, the systematic algorithm improvement of shared network data tamper prevention method is realized, and RDTP (Reliable Data Transfer Protocol) is selected in the network data of information sharing resources to realize the effectiveness of tamper prevention of air traffic control data during transmission. The results show that this method can reasonably avoid the tampering of information sharing on the Internet, maintain the security factors of air traffic control information sharing on the Internet, and the Central Processing Unit (CPU) utilization rate is only 4.64%, which effectively increases the performance of air traffic control data comprehensive security protection system.
