一种新的移动Ad hoc网络安全路由协议

Secure Routing for Mobile Ad hoc Networks

Buttyan L.等指出了移动Ad hoc网络典型安全路由协议Aridane的缺陷,并提出了一种自称可以抵御ac- tive-1-y(y≥1)型攻击的路由协议EndairA。文章通过分析发现EndairA不能抵御一种active-0-1型攻击,即中间人攻击,并据此提出了一种新的安全路由协议EndairALoc。分析表明EndairALoc不仅保持了EndairA原有的安全性,而且还能够抵御中间人攻击和虫洞攻击。另外该协议采用对称密钥机制替代了EndairA中使用的公钥签名机制,降低了安全路由所需的能耗。

Buttyan L. et al. found out a security flaw in Aridane and proposed a secure routing protocol, EndairA, which can resist attacks of active-1-1 according to ref^[9]. But unfortunately we discover an as yet unknown active-0-1 attack, ＂man-in-the-middle attack＂, which EndairA can＇t resist. So we propose a new secure routing protocol, EndairALoc. Analysis shows that EndairALoc can not only inherit security of EndairA, but also resist ＂man-in-the-middle attack＂ and even wormhole attack. Furthermore EndairALoc uses pairwise secret keys instead of public keys EndairA used, so compared with EndairA, EndairALoc can save more energy in the process of routing establishment.
