Cross-Layer Data Transmission Enhancement Techniques for Secure Communication

Le résumé fourni par la source

As the demand for secure data communication in cyberspace continues to grow, the concealment of the communication origin has become a critical indicator. Existing communication systems face issues such as static path structures and fixed communication exits, which pose risks of being cracked and interfered. This paper proposes and designs a data transmission enhancement system that integrates multiple network layers, including multi-path links at the transport layer, encrypted tunnels at the network layer, and routing mechanisms at the application layer. The system establishes a highly modular and orchestrable communication architecture with route perturbation capabilities. Experimental results show that the system achieves an average route establishment delay of 7.4 seconds, a$\text{1 0 0 \%}$IP switching success rate, a large-file packet loss rate of less than 1 %, and a 100 % data integrity rate—demonstrating high transmission security and high availability. This research aims to provide a practical, deployable, and highly scalable secure protection solution for the field of secure communications.
