Abstract : Mobile Ad hoc Network (MANET) is a wireless network of mobile nodes or mobile devices are connected without any specific infrastructure; it has the properties of self-configuration and self-maintenance nature, so it does not have any centralized control. The basic requirement for ad hoc network is to provide security. For providing authentication (trust) to the nodes, secure routing is the primary challenge. For improving the security, the most important thing is to examine the trustworthiness of nodes or mobile devices by identifying selfish and malicious nodes in the network. We are using the concept of trust and applying it on popular routing protocols of MANETs like DSR and AODV for providing secure routing. And also we are using the following algorithms, calculation of trust value (level) algorithm, identification of node misbehavior and modification of trust value algorithm, certificate distribution algorithm, and route innovation and maintenance algorithm for all the nodes in the network. Now, our concept of certificate-based trust and algorithms deals with the malicious nodes and provides a high secure routing.
