基于區(qū)塊鏈的車載命名數(shù)據(jù)網(wǎng)絡安全機制研究
發(fā)布時間：2020-12-03 08:13
命名數(shù)據(jù)網(wǎng)絡NDN通信模型中的“命名內(nèi)容”和“內(nèi)容自證實”機制使得它更適合于高速移動的車載自組織網(wǎng)絡,現(xiàn)有的車載命名數(shù)據(jù)網(wǎng)絡（V-NDN）方案能夠解決網(wǎng)絡遭受的某些傳統(tǒng)攻擊問題,但同時也引入了一些新的安全問題。網(wǎng)絡中任何惡意車輛節(jié)點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)點以備將來請求或發(fā)送虛假內(nèi)容以誤導其他車輛。另外,洪泛網(wǎng)絡中不存在內(nèi)容的請求會導致興趣洪泛攻擊,如與交通安全相關的虛假信息會造成交通事故等。因此,解決網(wǎng)絡中可能存在的惡意攻擊對車聯(lián)網(wǎng)安全至關重要。針對以上問題,本論文基于區(qū)塊鏈中信息具有不可篡改的特點,將網(wǎng)絡中與交通安全相關的通信作為“交易”信息并將其保存于區(qū)塊鏈中,這樣,可以對信息進行驗證和審計,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,設計了基于橢圓曲線密碼系統(tǒng)ECC的認證機制以及網(wǎng)絡中實體參與的許可區(qū)塊鏈,其中區(qū)塊鏈管理器驗證要加入網(wǎng)絡中的節(jié)點的身份,并將其身份信息和其他密碼學材料保存在區(qū)塊鏈存儲庫下的防篡改存儲中。2.為了驗證網(wǎng)絡中的車輛通信信息,設計了用于交通數(shù)據(jù)共享的通信協(xié)議,且只有...
