Nowadays the security assurance of information in Mobile Adhoc Networks (MANETs) is achieved by using secret keys. The dynamic and unpredictable nature of the network places challenges before the researchers in developing a suitable key generation method. Many of the present-day works aim at identifying passive attackers in the network and to protect the information from them. Active attackers are still posing difficulties in effective communication over Adhoc network. This paper proposes a point to point secret key generation scheme with the metadata traffic load suitable for Dynamic Source Routing (DSR) based MANETs. This work aims to extract correlated random data from the routing information and traffic matrix to develop a secret key and to study the effectiveness of this in identifying passive and active attackers. This scheme also ensures an optimum packet overhead and less computational complexity.

如今，通过使用私钥来实现移动自组织网络（MANET）中信息的安全性保证。网络的动态和不可预测的性质给研究人员开发合适的密钥生成方法带来了挑战。当前的许多工作旨在识别网络中的被动攻击者，并保护信息免受攻击。主动攻击者仍在通过Adhoc网络进行有效通信方面仍然构成困难。本文提出了一种适用于基于动态源路由（DSR）的MANET的，具有元数据流量负载的点对点秘密密钥生成方案。这项工作旨在从路由信息和流量矩阵中提取相关的随机数据，以开发出一个秘密密钥，并研究其在识别被动和主动攻击者方面的有效性。
