【摘要】：無(wú)線傳感網(wǎng)在許多大范圍監(jiān)測(cè)領(lǐng)域都有廣泛的應(yīng)用,在環(huán)境監(jiān)測(cè)、軍事偵察等領(lǐng)域都有規(guī)�；膽�(yīng)用。無(wú)線傳感器節(jié)點(diǎn)通常被部署在環(huán)境惡劣的無(wú)人值守區(qū)域,容易節(jié)點(diǎn)受損或者節(jié)點(diǎn)受攻擊,導(dǎo)致傳感網(wǎng)的傳輸受到嚴(yán)重影響。根據(jù)無(wú)線傳感器節(jié)點(diǎn)計(jì)算能力、存儲(chǔ)空間有限的特點(diǎn),我們?cè)O(shè)計(jì)了多跳長(zhǎng)路徑上多節(jié)點(diǎn)聯(lián)合的數(shù)據(jù)認(rèn)證機(jī)制,有效利用了數(shù)據(jù)認(rèn)證機(jī)制保障了傳輸路徑上的安全。深入研究了無(wú)線傳感網(wǎng)中數(shù)據(jù)認(rèn)證理論,設(shè)計(jì)實(shí)現(xiàn)了多跳長(zhǎng)路徑上多節(jié)點(diǎn)聯(lián)合數(shù)據(jù)認(rèn)證協(xié)議,進(jìn)行虛假數(shù)據(jù)過(guò)濾,有效限制了攻擊者利用妥協(xié)節(jié)點(diǎn)發(fā)動(dòng)共謀攻擊的威脅。并設(shè)計(jì)了路徑上節(jié)點(diǎn)關(guān)系的維護(hù)算法,保證了數(shù)據(jù)認(rèn)證機(jī)制的穩(wěn)定性。最后對(duì)協(xié)議的安全性能進(jìn)行了分析評(píng)價(jià)。針對(duì)多跳長(zhǎng)路徑上多節(jié)點(diǎn)聯(lián)合數(shù)據(jù)認(rèn)證協(xié)議的不足,對(duì)算法進(jìn)行了優(yōu)化,提出了多路徑抗節(jié)點(diǎn)失效機(jī)制和動(dòng)態(tài)步長(zhǎng)多節(jié)點(diǎn)聯(lián)合數(shù)據(jù)認(rèn)證機(jī)制。目標(biāo)是提升數(shù)據(jù)傳輸?shù)目煽啃?降低數(shù)據(jù)認(rèn)證機(jī)制的通信開(kāi)銷,并對(duì)優(yōu)化方案的安全性能進(jìn)行了分析評(píng)價(jià)。圍繞多跳長(zhǎng)路徑多節(jié)點(diǎn)聯(lián)合數(shù)據(jù)認(rèn)證機(jī)制的需求,對(duì)密鑰分配方案進(jìn)行了深入研究,提出了基于單向hash鏈的密鑰分配方案。對(duì)認(rèn)證中的MAC進(jìn)行了研究,提出了適應(yīng)數(shù)據(jù)認(rèn)證機(jī)制需求的MAC碼。通過(guò)仿真實(shí)驗(yàn)證明了本文中提出的方案的安全性能以及優(yōu)化效果達(dá)到了預(yù)期目標(biāo)。
[Abstract]:Wireless sensor network has been widely used in many fields in large-scale monitoring, environmental monitoring, military reconnaissance and other fields are applied. The scale of the wireless sensor nodes are usually deployed in unattended areas of poor environment, easy to damage or attack node node, sensor network transmission by computing power has been seriously affected. According to the characteristics of wireless sensor nodes, limited storage space, we design the authentication mechanism of data joint multi node multi hop path length, the effective use of data transmission security authentication mechanism on the path of data security. Wireless sensor network authentication theory deeply, the design and implementation of data combined with multi node multi hop authentication protocol long path, false data filtering, effectively limiting the attackers compromised node launched collusion attack threat. And the design of the relationship between the nodes on the path maintenance algorithm Method to ensure the stability of data authentication mechanism. Finally, the security performance of the protocol is analyzed. Aiming at the shortage of data combined with multi hop long path multi node authentication protocol, the algorithm is optimized, the multi paths of anti node failure mechanism and dynamic step multi node joint data authentication mechanism. The target is reliability to improve data transmission, reduce the communication overhead of data authentication, and the security performance of the optimization scheme is analyzed. The multi hop long path around the joint data multi node authentication mechanism needs to key distribution scheme is studied, put forward the key distribution scheme based on one-way hash chain authentication in MAC. The research, put forward to meet the demand of data authentication mechanism of the MAC code. The simulation results proved that the proposed scheme of safety performance and optimization effect reached the pre Target.
