*hi,*

*I am currently working with security in IBRDTN. I am using CORE (common open research emulator) platform, on which there two connected with a wired interface, nodes which run ibrdtn version 1.0.1 with the command dtnd -d 80 -c <path to ibrdtn.conf>. Both the nodes run same configuration file which is attached herewith.*

1. *Both the nodes are able to dtnping each other. * 2. *I use dtnsend --encrypt command with the specified file to the other node.* 3. *On wireshark capture of the whole setup there are no encrypted packets being exchanged, plain texts are observed in exchange between the nodes. * 4. *deamon debug logs have been listed here.* 5. *Additionally i also generated keys for both the nodes in etc/ibrdtn/bpsec folder the public/private key for both the nodes along with the default-bab-key.mac and; local.crt and local.key in /etc/ibrdtn/tls/ *

*Deamon log on the transmitting node dtn://n1/*
