Delay/Disruption Tolerant Networks (DTNs) have
been identified as one of the key areas in the field of wireless
communication, wherein sparseness and delay are particularly
high. These characteristics pose several challenges to the
security of DTNs. DTNs’ links on an end-to-end path do not
exist for a long time, and hence intermediate nodes may need to
store, carry, and wait for opportunities to transfer data packets
toward their destinations. Hence, DTNs are much more general
than MANETs in the mobile network space. A security
mechanism for DTNs is developed here which enables us to
evaluate the nodes based on their behavior during their past
interactions and to detect misbehavior due to Byzantine
adversaries, selfish nodes, and faulty nodes. An approach to
trust and reputation management is implemented which serves
to ensure secure communication and isolates malicious nodes
which may attack the network and reduces network performance
in terms of reliability and security.
