Hi folks,

  at the last IETF we gave a presentation about "Threats in 
Content-Centric Routing". We updated our technical report, which 
discusses these aspects in more detail: http://arxiv.org/abs/1205.4778v2

  Core changes include:

  * analytical model to quantify the state complexity (Section 3.2.1).
We emphasize that this depends not only on the RTT but also on the RTT
variation.

  * detailed discussion on PIT state table management w.r.t. the data
structure in use (Section 3.2.3).

  * discussion on rate limiting, which can be used to mitigate interest 
flooding but then reduces network utilization and introduces easily new 
attack vectors (Section 5.1).

  * extended experiments.

  Comments are very welcome!

Cheers
  matthias
