在赛博空间的攻防博弈中,信息系统的静态不变特性使得攻击者具有足够的时间和空间来实施侦察、发动攻击.从网络防御的角度来看,利用操作系统、软件、数据、网络设施的动态随机变化实现信息系统的动态防御,有可能减小攻击面,从而抑制攻击... 在赛博空间的攻防博弈中,信息系统的静态不变特性使得攻击者具有足够的时间和空间来实施侦察、发动攻击.从网络防御的角度来看,利用操作系统、软件、数据、网络设施的动态随机变化实现信息系统的动态防御,有可能减小攻击面,从而抑制攻击.基于马尔可夫(Markov)链模型对信息系统动态目标防御方法进行了建模分析,通过引入攻击探测概率指标对变化攻击面进行定量度量.根据攻防博弈中实施策略的不同,将模型细分为4种情况,并以动态云中心攻防为例,对模型的有效性和合理性进行了验证. 展开更多

The combat survivability is an essential factor to be considered in the development of recent military aircraft. Radar stealth and onboard electronic attack are two major techniques for the reduction of aircraft susceptibility. A tactical scenario for a strike mission is presented. The effect of aircraft radar cross section on the detection probability of a threat radar, as well as that of onboard jammer, are investigated. The guidance errors of radar guided surface to air missile and anti aircraft artillery, which are disturbed by radar cross section reduction or jammer radiated power and both of them are determined. The probability of aircraft kill given a single shot is calculated and finally the sortie survivability of an attack aircraft in a supposed hostile thread environment worked out. It is demonstrated that the survivability of a combat aircraft will be greatly enhanced by the combined radar stealth and onboard electronic attack, and the evaluation metho dology is effective and applicable. 展开更多
