Abstract: A delay tolerant network (DTN) depends on certain assumptions that nodes cooperate and coordinate towards message forwarding. However, this assumption cannot be satisfied if there are malicious nodes in the network these malicious nodes intentionally attract and drop messages from other nodes of the network. In this paper we propose a scheme for preventing malicious nodes from launching the combination of Routing Misrepresentation and Sybil attacks. This scheme is based on identity based digital signature scheme. Each node in a network needs to verify its identity before taking an interest in the message exchange process. The proposed system is utilised to secured prophet routing protocol (SPRP) against the combination of routing misrepresentation and Sybil attacks. The resulting protocol is robust against these combinations of attacks.
