| 摘 要： | 针对Savage等人提出的分片包标记方案(fragment marking scheme,FMS)存在的不足,提出一种改进的分片包标记方案(IFMS),该方案通过扩大标记空间和采用动态标记概率的方法,减少了重构攻击路径所需的数据包数,降低了计算开销,同时采用40位Hash作为误差校验,显著降低了路径重构的误差率.理论分...

| Abstract: | Aimed at the inadequaey resident in the fragment marking scheme proposed by Savage et al.an improved fragment packet marking scheme(IFMS) was presented.By enlarging marking space and using dynamic probability of packet marking,the number of data packets required by the victim to reconstruct the attack path and the computational complexity were reduced.Meanwhile,40 parity-check bits generated by 2 different Hash functions were employed to reduce greatly the rate of false alarm during the process of path reco... |
