基于生命周期理论的军事环境安全策略

探讨了军事环境安全概念,并运用生命周期理论对国家军事环境安全的保障措施和宏观策略进行了初步研讨。军事活动一般可分为计划规划、具体实施和事后评价3个阶段。为了在新形势下更加经济、高效地保障国家军事环境安全,首先要加大军事活动环境影响评价力度、采用对环境破坏小的战法并在军购中推行环境准入制,即尽量从源头上控制重大环境问题出现。考虑到战争的特殊性,需要在战前预先储备必要的生态环境修复技术。

基于CA的电子印章系统设计与实现

针对分布式层次化网络安全应用,提出了一种分布式简化严格层次结构的PKI信任体系模型,为网络应用提供有效的认证、访问控制、授权、机密性、完整性、非否认服务。在该信任体系模型基础上,提出并建立了由CA签发的发章证书概念,来保证CA所辖域中印章文件的安全。系统通过CA签发的电子印章来对网络中电子公文和印章文件进行数字签名、验证,并由加密证书保护电子公文加密密钥,通过授权服务器管理用户打印印章权限。     

网络安全脆弱性分析与处置系统的研究与实现

在分析国内外研究现状的基础上,针对现有的漏洞库系统在漏洞信息的组织、使用等方面存在的不足,采用分布计算技术、数据库技术、Web技术实现了网络安全脆弱性分析与处置系统。该系统实现了基于Web的漏洞库(含补丁库)的访问与维护工具,便于获取相应漏洞的解决方案和下载相应的补丁程序,降低了系统维护的开销,提高了系统的可维护性;补丁推送程序实现了对系统补丁程序的远程推送、漏洞修补和补漏检测,提高了系统的自动化程度,为网络安全脆弱性处置提供了有力工具。

The elephant in the room: US ballistic missile defence under Barack Obama

Conventional wisdom seems to hold that under Barack Obama, the US ballistic missile defence programme has been pushed aside to allow for a refreshed domestic and international agenda. Proponents point to Obama's campaign thinking and rhetoric, the ballistic missile defence (BMD) budget cuts, the decision to end the Third Site in Europe, and the reset relations with Russia through the New Strategic Arms Reduction Treaty (New START) as evidence that the programme has undergone a significant period of change, retraction and rationalisation. This article argues instead that BMD has not fallen from prominence and that there is a change in focus rather than retraction of its strategic goal. Consequently, BMD continues to grow in importance as a component of US national security strategy.     

无人机配载弹射式导弹静稳定性分析

通过刚体飞行六自由度动力学方程建立弹射式导弹初始段无控飞行模型,并结合弹射装置动力模型和导弹发动机推力模型进行仿真计算。基于无控飞行模型和仿真结果分析了无人机配载弹射式导弹发射特性,在导弹初始飞行段对机弹分离安全性和导弹姿态控制要求进行了研究。对导弹不同静稳定度下的运动特性对比分析,分别给出了满足各种安全和控制要求的导弹静稳定度范围。进一步综合所有安全和姿态控制要求,得到了满足所有要求的最佳静稳定度。经过一个实例的仿真研究,结果表明建立的模型与所用到的方法是合理有效的。     

Maritime interdiction in Sri Lanka's counterinsurgency

A comprehensive maritime interdiction strategy to attack the insurgent's logistic system was a key element in the defeat of the Tamil Tigers. The campaign of maritime interdiction required the Sri Lankan Navy (SLN) to attack LTTE arms smuggling, sea piracy, and maritime terrorism. The SLN degraded the insurgency's robust maritime logistical network while also devising tactics to engage the maritime insurgents who reacted with swarm and suicide boat tactics. The efforts of the SLN forced the Tamil Tigers to confront the government's final land offensives with diminished resources, thus collapsing a three decades’ old insurgency in a matter of months.     

At war with social theory: Instrumental and communicative action in US military doctrine during the War on Terror

As US counterinsurgency campaigns draw to a close, doctrine for asymmetric warfare written during the War on Terror has come under heavy criticism. While many have argued that this shift to ‘winning hearts and minds’ is evidence that the United States is taking humanitarianism and nation-building seriously, others argue that a wide gap exists between US counterinsurgency doctrine and the protection of civilians afflicted by conflict. In this article, I show that the latter is true by comparing theories of instrumental and communicative action to US doctrine for operational design, stability operations, and counterinsurgency. I argue that these texts treat the people as an object to be manipulated for the achievement of pre-determined self-interested strategic goals rather than members of a community that jointly designs operations to fulfill shared objectives. However, US doctrine does contain communicative elements that, if prioritized, would better support humanitarian and state-building objectives otherwise subordinated in the War on Terror.
