摘　　要：网络层安全是移动自组网安全的一个基本方面。过去,人们对移动自组网网络层安全的研究主要集中在使用密码体制来保护路由消息的真实性和完整性上。但是,密码学体制所带来的额外资源开销和延时比较大。因此,移动自组网需要一种轻权的网路层安全机制。本文提出了一种基于跨层的移动自组网安全路由协议,利用跨层信息来提高网络层的安全性。模拟实验表明,我们所提出的安全路由协议是有效的。Network layer security is one of the fundamental aspects of security in mobile ad hoc networks. Traditional work in this aspect mainly focuses on protecting the authenticity and integrality of routing messages through a cryptography mechanism. But the additional resource consumption and delay introduced by cryptographic operations are intolerable for users. In this paper, we propose a light-weight cross-layer secure routing protocol which improves the security of mobile ad hoe networks through exploiting the cross-layer security features at different layers of the protocol stack. Our proposal does not rely on any established cryptography infrastructure. Simulation results show the effectiveness of the proposed secure routing protocol.
