| 摘 要： | 根据移动自组网(MANET)中常见的路由协议安全威胁，结合卫星网络的特性，分析辅助定位按需路由(LAOR)协议可能存在的安全问题，得出LAOR协议安全改进的要点，通过引入基于身份的密码体制以实现节点间路由控制分组的相互认证，并利用节点私钥对路由控制分组签名以保护路由控制分组的完整性。利用串空间对改进后的路由协议进行分析，并证明它满足plausible routing，是安全的。

| Abstract: | This paper referred to the common routing protocol threats appearing in MANET and analyzed the properties of satellite network to get possible security threats of Location-Assisted On-demand Routing (LAOR) and what to do to make the protocol safer. It used Id-based cryptography to mainly realize mutual authentication between nodes and protection of the integrity of routing control packet by signature using each nodes private key. Finally strand space was used to analyze the improved routing protocol, and proved it satisfied plausible routing, and was secure. |
