Abstract: High real-time mobile video stream cross-domain secure transmission and sharing has become a research focus in the field of high-performance and secure communication. In this study, a more efficient method based on combining a zero-copy model with a one-way light transmission mechanisms is proposed. The method contains an effective integrated framework and layered design structure. The latest PF_RING (9.0.0) zero-copy model, memory routing table, multi-queue multi-threading, and related technologies are comprehensively combined to ensure the high-performance cross-domain secure transmission and sharing of video streams. At the same time, to ensure the safe transmission of shared mobile video data between different network domains, both a mobile video surveillance data transmission model and an anti-storage-based covert channel model are proposed. The experimental results show that the performance of the proposed method has increased by at least 10% in throughput, central processing unit utilization, and bit error rate.
