Hi,
If we want to define the security threat model for DTN overall, then we have to consider all the possibilities while defining the security threat model.  We can assume any level of adversary with any level of power or control over the communication.. If we say, we have to provide following services or have to defend against attacks as given below (taken from different DTN internet drafts) .. 

     1- high level of confidentiality 
     2- Modification attack 
     3- Replay Attack, 
     4- Reflection attack, 
     5- Certificate modifications 
     6. Non-DTN threats possibly injections into dtn bundle layer.. 
     7. Have to stop the cause for traffic storms.. 

Different protocols being defined should at least try to defend the above defined attacks for DTN overall.. Can there be any different perspective for defining threat model for DTN networks.. 

Any comment will be appreciated.. 

regards,
Nasir
