【摘要】：針對采用單一掃描策略的傳統(tǒng)蠕蟲無法在IPv6網(wǎng)絡(luò)及有網(wǎng)絡(luò)地址轉(zhuǎn)換設(shè)備存在的網(wǎng)絡(luò)中快速傳播的問題,提出了一種新型的蠕蟲分層掃描策略,即在本地應(yīng)用基于Teredo服務(wù)的子網(wǎng)內(nèi)掃描策略,在子網(wǎng)間應(yīng)用基于搜索引擎的掃描策略。通過對經(jīng)典的簡單傳染病蠕蟲傳播模型進(jìn)行補(bǔ)充與修改,在推導(dǎo)出了蠕蟲傳播速度公式的基礎(chǔ)上分析與預(yù)測了使用這種掃描策略的蠕蟲的傳播狀況。仿真實(shí)驗(yàn)結(jié)果證明,使用這種新型掃描策略的蠕蟲與其他蠕蟲相比,在復(fù)雜網(wǎng)絡(luò)環(huán)境中感染外網(wǎng)中主機(jī)所花費(fèi)的時(shí)間僅為傳統(tǒng)蠕蟲的10%,即有更快的傳播速度與更大的傳播范圍。
[Abstract]:Aiming at the problem that the traditional worm with single scanning strategy can not propagate rapidly in IPv6 network and network with network address translation device, a new layered worm scanning strategy is proposed. That is to say, the local application is based on the Teredo service in the subnet scanning strategy, and in the subnet application based on search engine scanning strategy. By supplementing and modifying the classical model of worm propagation of simple infectious diseases, the propagation status of worms using this scanning strategy is analyzed and predicted on the basis of deducing the formula of worm propagation speed. The simulation results show that compared with other worms, the worm using this new scanning strategy only spends 10 times as much time as the traditional worm in the complex network environment, that is, it has a faster propagation speed and a larger propagation range.
