公安现役部队文化建设途径探析

加强公安现役部队文化建设,必须把握文化建设的方向,坚持社会主义核心价值体系,坚持抵制腐朽文化的影响和继承与创新的统一;必须抓住文化建设的关键环节,坚持以人为本,注重结合部队职能任务,建设学习型警营;必须筑牢文化建设的基础支撑,注重队伍建设,加大基础设施建设和制度建设。     

试析世博安保中的军事“软实力”运用

世博会的圆满召开,不仅需要强大的军事“硬实力”作后盾,也需要军事“软实力”作支撑。本文从军事“软实力”的基本概念入手,将其分解为感化认同力、形象吸引力、心理威慑力等三个子要素;从各要素出发,以完成世博安保任务为着眼点,提出加强军事“软实力”的具体思路。     

Information security: Designing a stochastic‐network for throughput and reliability

Todas information and communication network requires a design that is secure to tampering. Traditional performance measures of reliability and throughput must be supplemented with measures of security. Recognition of an adversary who can inflict damage leads toward a game‐theoretic model. Through such a formulation, guidelines for network designs and improvements are derived. We opt for a design that is most robust to withstand both natural degradation and adversarial attacks. Extensive computational experience with such a model suggests that a Nash‐equilibrium design exists that can withstand the worst possible damage. Most important, the equilibrium is value‐free in that it is stable irrespective of the unit costs associated with reliability vs. capacity improvement and how one wishes to trade between throughput and reliability. This finding helps to pinpoint the most critical components in network design. From a policy standpoint, the model also allows the monetary value of information‐security to be imputed. © 2009 Wiley Periodicals, Inc. Naval Research Logistics, 2009     

基于LBDL逻辑的抗DPA攻击电路设计方法

动态差分逻辑是一种典型的电路级差分功耗攻击(DPA)防护技术.这种技术通过使逻辑门保持恒定的翻转率来降低电路功耗与数据信号之间的相关性.介绍了一种新型的、基于查找表(Look-Up-Table,LUT)结构的动态差分逻辑(LBDL),以及基于这种逻辑的集成电路设计方法.该设计方法仅需在传统的半定制设计流程中添加少量的替换操作就可以实现 ,因而比其他完全需要全定制设计的动态差分逻辑具有更好的实用性.而相对同样适用于半定制实现的动态差分逻辑 WDDL(Wave Dynamic Differential Logic),LBDL逻辑解决了逻辑门翻转时刻与数据信号之间的相关性,从而比WDDL逻辑具有更好的功耗恒定性.实验结果表明,该设计方法能够有效实现具有抗DPA攻击性能的电路.     

The Somali National Army: an assessment

To engage properly with the Somali National Army, to understand it in the hope of improving stability and the lives of over 12 million Somalis, good basic information on its composition and characteristics is necessary. Authoritative accounts on the subject have been scarce for over 25 years. This account seeks to detail the army’s dispositions across southern Somalia, and, more importantly, the brigades’ clan compositions and linkages. Clan ties supersede loyalties to the central government. The army as it stands is a collection of former militias which suffer from ill-discipline and commit crime along with greater atrocities. Estimates of numbers are unreliable, but there might be 13,000 or more fighters in six brigades in the Mogadishu area and five beyond.     

Collective security and strategic instability in the digital domain

Cyberspace experiences worrying trends that could have a negative impact on the international strategic landscape. The lack or erosion of norms and risky practices and behaviors could lead to greater uncertainty and thus greater instability. Set against a context of renewed competition between great powers, these developments are also tied to the strategic structure of cyberspace. This forum is devoted to discussing factors leading to stability or and instability.     

一种改进的事件驱动系统框架

在给出事件驱动系统安全漏洞的基础上,指出了产生漏洞的根本原因是:系统忽视了输入系统的事件序列之间存在的相关性;系统无条件信任任何事件源产生的事件.针对这两个原因,相应提出了事件序列形式安全分析模型及基于事件源的可信度评估模型,依据这两个模型,构建了一种改进的事件驱动系统框架.     

装备研制中技术风险的灰色综合评估

指出装备研制中技术风险的表现形式,建立了技术风险评估的指标体系,阐述了基于灰类白化权函数将定性指标定量化的方法,建立了利用群灰关联度进行综合评估的模型。最后,结合实例验证说明了该模型对研制方案技术风险评估的可用性。     

风险评价在军队营区环境管理中的应用

分析了军队营区环境风险的概念,认为要消减军队营区环境风险,不能仅考虑降低风险概率或风险后果,而应从风险概率与风险后果两者的乘积效应出发,通过综合分析和控制环境风险系统来解决;着重探讨了军队营区环境风险评价的内容和方法,包括环境风险识别、环境风险预计、环境风险评价与对策.军队营区环境风险评价可从二个层次进行评价一是从事件及与之有关联的周围环境条件出发,按"环境风险系统"的思路,从风险源、初级控制条件、二级控制条件、目标4个阶段进行评价;二是从事件或行动的具体问题出发,评价其风险的重大性和可接受性.最后讨论了军队营区环境风险管理的内容和方法.
