CSRP: A Centralized Secure Routing Protocol for mobile ad hoc network

Security in MANET is a grand challenge problem nowadays. The main security issues in MANET are identification and privacy. To combat with these problems, many secure routing protocols have been designed to reduce the security threats. In this paper, we have proposed a Centralized Secure Routing Protocol (CSRP) to enhance the security levels in the architecture to prevent the network against active and passive attacks. A Master Node (MN) is used in this architecture to control and manage the network security and data delivery. In the first step we have recognized the nodes and in the second step we have established session keys between the nodes for safe communication. The data delivery is done by encryption/decryption mechanism using session key. CSRP algorithm is mainly designed for secure and safe routing.
