摘要：Delay Tolerant Networking (DTN) program is an emerging technology that can facilitate access to information when secure end-to-end paths cannot exist. DTNs may be turn into vulnerable during the legitimate nodes may compromise and the attacker modifies or alters the delivery constraints of the node. DTN makes use of persistence within the network nodes along with the mobility strategy to overcome the delay for connectivity. The existing trust management protocols are not an effective approach to handle the security attacks. In this paper, an efficient approach termed as a Repetitive Trust Management (RTM) and Adversary Detection is proposed to handle the Byzantine attacks in DTNs. It takes into consider the reputation values among the nodes participated in the data transmission. Bipartite graph is utilized to represent the subset of the nodes participate in the network. Trust Based Management Classifiers is presented which uses the Bloom filter to check the hash functionalities between the nodes. Here, threshold mechanism is used to enhance the secure communication in DTNs. The experimental results proves that the proposed scheme detects the malicious nodes and recovers the message within short duration of time.
