Hello,
When we design a secure system, the security should be provided at each = layer to make a good secure system.
If we develop a system on top of DTN based network, then which layer = will be best suitable to provide security extensions. 

Suppose, we have underlying sensor network and on top DTN as overlay = network, which layer we should provide the security services
for such system.  I think, to get benefits like, generic solution, = we should introduce security extensions to bundle layer ...

            &= nbsp;           &n= bsp;    Bundle Layer

Please comment on this and appropriate suggestions for building a = security architecture for overlay network on top of sensor networks.
