未来战术通信网络将使用VHF／UHF无线电进行语音和数据通信，战术通信网络相对固网而言，具有低带宽、高误码率和节点移动性的特点。由于组网对战术通信而言相对较新，其安全性尚未得到完备的考虑，尽管移动Adhoc网络（MANETs）的安全威胁已经被广泛研究，但是不同通信手段具有不同的特点，其安全威胁不一定类似。文中通过分析已有的MANET安全威胁提出了一种新的方法，以评估其对战术网络的潜在影响。尽管这些分析并不覆盖所有可能的威胁，但它具有优势并且能定位主要问题。基于这个分析，提出一个分层的服务框架并集成各层的安全功能。

The future tactical network would, with VHF/UHF-band radios, implement multi-hop digitized voice and data communications. And this radio band, with excellent propagation property and node mobility, is relatively low in bandwidth and high in error rate, thus making the tactical radio less than ideal as a robust networking platform. Since networking is fairly new to tactical communications, the security implications are not fully understood. Although significant research is done on the threats and vulnerabilities of commercial mobile Ad-hoc networks（MANETs）, the threats described in the literature are not always identical due to different communications characteristics. This paper, by reviewing the known MANET security threats, proposes a novel approach to evaluating their potential impact on tactical networks. This analysis, although could not cover all possible security threats, is of certain superiority in identifying the most critical areas for further research. Based on this analysis, a cross-layer service framework is proposed to integrate security functions across all communication layers. This framework, including its application in several security areas, is also described in this paper.
