網(wǎng)絡(luò)攻擊防御對策研究.pdf

1、摘要文章研究一類包含網(wǎng)絡(luò)設(shè)計(jì)者和攻擊者的非合作對策。從網(wǎng)絡(luò)設(shè)計(jì)出發(fā)，假設(shè)網(wǎng)絡(luò)的設(shè)計(jì)者同時(shí)承擔(dān)網(wǎng)絡(luò)防御的任務(wù)，針對網(wǎng)絡(luò)設(shè)計(jì)、防御和攻擊發(fā)生的所有時(shí)序關(guān)系，系統(tǒng)研究設(shè)計(jì)者根據(jù)每個(gè)階段攻防結(jié)果所實(shí)施的設(shè)計(jì)動(dòng)態(tài)。論文的主要貢獻(xiàn)是分別給出了單階段及多階段的動(dòng)態(tài)網(wǎng)絡(luò)設(shè)計(jì)、防御和攻擊所應(yīng)遵循的一些基本準(zhǔn)則。文章的創(chuàng)新性在以下幾個(gè)方面均有體現(xiàn)。第一，提出了在單階段網(wǎng)絡(luò)設(shè)計(jì)問題、多階段網(wǎng)絡(luò)設(shè)計(jì)問題下的關(guān)于支付、成功攻擊、攻擊在路徑間傳播的假設(shè)，并通過詳盡

2、的網(wǎng)絡(luò)圖和支付表來證明主要結(jié)論。第二，對于單階段的網(wǎng)絡(luò)設(shè)計(jì)問題，給出了當(dāng)給定網(wǎng)絡(luò)中的節(jié)點(diǎn)數(shù)目、防御以及攻擊資源時(shí)設(shè)計(jì)者最優(yōu)的網(wǎng)絡(luò)結(jié)構(gòu)設(shè)計(jì)方式；同時(shí)給出了攻擊資源和防御資源相對于節(jié)點(diǎn)數(shù)目較大時(shí)的關(guān)于均衡網(wǎng)絡(luò)結(jié)構(gòu)的定理。第三，針對網(wǎng)絡(luò)設(shè)計(jì)者提出并建立了全局最優(yōu)準(zhǔn)則，即多階段動(dòng)態(tài)網(wǎng)絡(luò)設(shè)計(jì)情形下設(shè)計(jì)者面對策略攻擊或隨機(jī)攻擊時(shí)的支付總和最大化原則，而假設(shè)網(wǎng)絡(luò)攻擊者致力于階段支付最大化的結(jié)果。關(guān)鍵詞：動(dòng)態(tài)網(wǎng)絡(luò)設(shè)計(jì)；攻擊；防御；DDA對策；DAD對策
