An Energy-Efficient Technique to Combat DOS Attacks in Delay Tolerant Networks
<06>The paper presents a new solution to the difficult security problem of Denial of Service (DoS) attacks in the highly constrained DTN environment. The novelty of the paper is the introduction of three DTN-cookie variants for DTN hop-by-hop authentication. The paper proposes a scheme that can identify and drop bogus packets from the attacker, block attack packets from being processed and does not introduce a new availability problem when activated. The proposed mechanisms are lightweight and hard to forge. This work will feed into security standards for DTN (e.g. IETF and DTNRG). This was an invited paper to the journal.
