摘要
剖析了多跳Ad hoc网络AODV与DSR路由协议的安全漏洞,并指出安全路由协议的设计需求。本文详细介绍了一种Ad hoc的鉴别路由协议ARAN,该协议采用公钥密码技术,利用节点对路由消息的签名,有效地抵制了各种恶意攻击,虽然在某种程度上增加了计算复杂度,提高了节点存储量,但仍不失为一种有效的按需安全路由协议,可以满足无线多跳Ad hoc网络在各种应用领域对路由的安全需求。
Security threats against Ad hoe routing protocols were introduced in terms of AODV and DSR used as representatives of multi-hop Ad hoe on-demand protocols. In order to guard against these attacks, security requirements for Ad hoe routing design were described and an Authenticated Routing for Ad hoc Networks （ARAN） was detailed. This current protoeol exploited asymmetric cryptographic operations and its routing messages were signed by node＇s private key, so it successfully defeated many different types of identified attacks. Although ARAN has some disadvantages on computing complexity and memory size, it is a sufficient on-demand security routing protocol and can satisfy security muting requirements for various applications.
