基于簇结构的AdHoc网络密钥管理方案

Cluster-based Key Management Scheme for Ad Hoc Networks

在分析现有的Ad Hoc网络分布式信任方案基础上,提出一种有效的基于簇的密钥管理方案。该方案实现了节点之间的双向认证,具有较强的抗假冒攻击能力和抗重放攻击能力,防止了由于通信一方指定会话密钥产生的安全隐患。仿真结果表明,该方案安全高效,适合主机能量与计算能力受限、通信带宽有限的移动Ad Hoc网络。

Following the analysis of existing distributed trust model to Ad Hoe networks, this paper proposes an effective key management scheme based on cluster. The scheme achieves two-way authentication between the nodes, with strong capability of anti-counterfeiting attack and anti-replaying attack, and prevents the security risks because of the communications party designating session key performance of simulations shows that the scheme is secure and effective. The scheme is suited to Ad Hoe network which restrict the host energy, computing power and communications bandwidth as well.
