A Survey on Various Security Issues in Delay Tolerant Networks

Priya Pathak, Akansha Shrivastava, Sandeep Gupta


Security is one of the major threats in Delay tolerant network (DTN). The DTN communication takes place when if it is in the range of communication. Hence due to this shortcoming there exists possibility of dropping the delivered messages by the selfish or malicious nodes, which result to attacks. Various security attacks such as; black hole, wormhole, grey hole etc. effect the network connectivity as well as increase the delay. Apart from these attacks various open issues are also present namely; key management, routing protocol security, multicast routing etc. These issues have severe effects on the routing protocols. To make secure, reliable communication it is necessary to overcome all these issues. Various schemes have been implemented but none provide a fair solution for these issues. In this paper we have studied these issues, various security threats, security requirements, and characteristics.
