A file transfer method and system for crossing security isolation gateways
Chenguo Luo, Naixiang Ao · 2024
In this paper, a novel file transfer method and cross-security isolated gateways system are developed to improve the efficiency of file transfer across secure net gates. The system introduces a cross-security gateway file receiving proxy and a cross-security gateway file sending proxy based on the secure file transfer of the information security exchange platform. The cross-net gate file receiving proxy handles unstructured data files by using slicing, concurrency, and compression, while for structured data files, a feedback file transfer algorithm is used to achieve adaptive file transfer. The system also ensures the reliability of cross-net gate transfers through a retransmission confirmation mechanism. This system has successfully achieved fast, stable and reliable file transfer across secure net gates and has been applied in several adaptive next-generation scheduling system projects.
