命名數(shù)據(jù)網(wǎng)絡(luò)NDN通信模型中的“命名內(nèi)容”和“內(nèi)容自證實(shí)”機(jī)制使得它更適合于高速移動(dòng)的車載自組織網(wǎng)絡(luò),現(xiàn)有的車載命名數(shù)據(jù)網(wǎng)絡(luò)（V-NDN）方案能夠解決網(wǎng)絡(luò)遭受的某些傳統(tǒng)攻擊問題,但同時(shí)也引入了一些新的安全問題。網(wǎng)絡(luò)中任何惡意車輛節(jié)點(diǎn)通過觀察興趣分組和數(shù)據(jù)分組中的內(nèi)容名稱來生成虛假的內(nèi)容,并緩存于中間節(jié)點(diǎn)以備將來請(qǐng)求或發(fā)送虛假內(nèi)容以誤導(dǎo)其他車輛。另外,洪泛網(wǎng)絡(luò)中不存在內(nèi)容的請(qǐng)求會(huì)導(dǎo)致興趣洪泛攻擊,如與交通安全相關(guān)的虛假信息會(huì)造成交通事故等。因此,解決網(wǎng)絡(luò)中可能存在的惡意攻擊對(duì)車聯(lián)網(wǎng)安全至關(guān)重要。針對(duì)以上問題,本論文基于區(qū)塊鏈中信息具有不可篡改的特點(diǎn),將網(wǎng)絡(luò)中與交通安全相關(guān)的通信作為“交易”信息并將其保存于區(qū)塊鏈中,這樣,可以對(duì)信息進(jìn)行驗(yàn)證和審計(jì),提出了一種解決上述安全問題的BV-NDN方案。本論文主要研究工作如下:1.為了建立網(wǎng)絡(luò),設(shè)計(jì)了基于橢圓曲線密碼系統(tǒng)ECC的認(rèn)證機(jī)制以及網(wǎng)絡(luò)中實(shí)體參與的許可區(qū)塊鏈,其中區(qū)塊鏈管理器驗(yàn)證要加入網(wǎng)絡(luò)中的節(jié)點(diǎn)的身份,并將其身份信息和其他密碼學(xué)材料保存在區(qū)塊鏈存儲(chǔ)庫(kù)下的防篡改存儲(chǔ)中。2.為了驗(yàn)證網(wǎng)絡(luò)中的車輛通信信息,設(shè)計(jì)了用于交通數(shù)據(jù)共享的通信協(xié)議,且只有...
