【摘要】：為了解決當(dāng)前車載網(wǎng)隱私保護(hù)機(jī)制的安全性和效率問(wèn)題,基于安全多方計(jì)算理論和匿名認(rèn)證協(xié)議,提出了一種新的車載網(wǎng)節(jié)點(diǎn)隱私保護(hù)方案.該方案利用線性方程組的求解理論,采用安全高效的茫然傳輸機(jī)制,避開(kāi)了傳統(tǒng)的計(jì)算復(fù)雜的公鑰密碼算法.對(duì)方案的安全性和效率分析的結(jié)果表明,新方案不僅能夠解決車載網(wǎng)中發(fā)送者隱私、接收者隱私、匿名性、共謀攻擊、重放攻擊等多種安全問(wèn)題,而且認(rèn)證效率也得到了有效提高,在計(jì)算性能受限的物聯(lián)網(wǎng)環(huán)境中,具有理論和應(yīng)用價(jià)值.
[Abstract]:In order to solve the security and efficiency problems of the current privacy protection mechanism of vehicular network, based on the theory of secure multi-party computing and anonymous authentication protocol, In this paper, a new privacy protection scheme for vehicular network nodes is proposed, which utilizes the solution theory of linear equations and adopts a secure and efficient blankly transmission mechanism. The results of security and efficiency analysis show that the new scheme can not only solve the privacy of sender, receiver, anonymity, collusion attack, but also can solve the problem. Replay attacks and other security problems, and the efficiency of authentication has been effectively improved, in the computing performance of the Internet of things environment, has theoretical and application value.
