無(wú)線傳感器網(wǎng)絡(luò)中基于節(jié)點(diǎn)行為和身份的可信認(rèn)證

     

摘要

Concerning the vulnerability to attack from external and internal nodes and node failure due to openness and limited resources in Wireless Sensor Network (WSN),an efficient,secure trusted authentication scheme was proposed.The theory of identity-based and bilinear pairings was adopted in the authentication key agreement and update.The node trust value was computed by node behavior reputation management based on Beta distribution.The symmetric cryptosystem combined with message authentication code was used in certification process between trusted nodes which were identified by the trust value.The scheme not only can prevent eavesdropping,injection,replay,denial of service and other external attacks,but also is able to withstand internal threats such as the selective forwarding,Wormhole attack,Sinkhole attack and Sybil attack.The analysis and comparison with SPINS scheme show that the scheme can achieve longer network lifetime,smaller certification delay,greater security and scalability in the same network environment.The scheme has good application value in unattended WSN with high safety requirements.%針對(duì)無(wú)線傳感器網(wǎng)絡(luò)(WSN)開(kāi)放性和資源受限導(dǎo)致易受外部和內(nèi)部攻擊以及節(jié)點(diǎn)失效等問(wèn)題,提出了一種高效、安全的可信節(jié)點(diǎn)間身份認(rèn)證方案.方案采用基于身份和雙線性對(duì)理論實(shí)現(xiàn)認(rèn)證密鑰協(xié)商與更新,通過(guò)基于Beta分布的節(jié)點(diǎn)行為信譽(yù)的管理計(jì)算其信任度,利用信任度識(shí)別節(jié)點(diǎn)是否可信并采用對(duì)稱密碼體制結(jié)合信息認(rèn)證碼實(shí)現(xiàn)可信節(jié)點(diǎn)間認(rèn)證.方案不僅能防范竊聽(tīng)、注入、重放、拒絕服務(wù)等多種外部攻擊,而且能夠抵御選擇性轉(zhuǎn)發(fā)、Wormhole攻擊、Sinkhole攻擊和女巫攻擊等內(nèi)部威脅.與SPINS方案相比,所提方案在同一網(wǎng)絡(luò)環(huán)境下有較長(zhǎng)的網(wǎng)絡(luò)生命期、較小的認(rèn)證時(shí)延、更高的安全性及可擴(kuò)展性,在無(wú)人值守安全性要求較高的WSN領(lǐng)域具有較好的應(yīng)用價(jià)值.
