临近空间网络安全切换机制研究

Research on security-handoff of near-space network

近年来随着空间网络应用的快速发展,临近空间网络逐渐成为新的研究热点。高度暴露、动态组网、通信能力受限的临近空间网络要求高实时性、高安全性移动安全接入,具有频繁的入/退网、频繁切换的特点,对切换效率与安全提出了更高的要求。提出了一种临近空间网络安全切换机制,给出了安全切换的定义、内涵,分析了安全切换与传统切换、切换安全的不同之处,并设计了MPHR选择算法与信任传递机制,实现了安全通道的整体切换与安全通信的连续性,在保证安全性的同时有效提高了切换效率,减少了临近空间网络的安全切换延时。

The near-space network has become of research focus with rapid developing of space network.With characteristic of high exposure,dynamic establishing net,finity capability of calculate,near-space network demand higher real time,security.This thesis put forward a security-handoff of near-space network,introduce the definition and meaning of security-handoff,and analyse the difference compare of tradition handoff,security handoff,and handoff-security.This thesis also design the selection arithmetic of MPHR and trust transfer mechanism,that realize handoff of security channel and continuity of security communication,and that can ensure security and advance efficiency of handoff.
