Raju, P.R.Shet, K.C.2020-03-302020-03-302012Proceedings: Turing 100 - International Conference on Computing Sciences, ICCS 2012, 2012, Vol., , pp.379-383https://idr.nitk.ac.in/handle/123456789/7462In this paper, we propose a new scheme for mitigating the persistent packet reordering attack. This attack mainly makes use of the end to end congestion control mechanism of TCP. The proposed scheme uses symmetric key cryptography and modified SHA-1 (mSHA-1) hash function for verifying packet reordering. This is implemented with AOMDV routing protocol using NS-2 network simulator. The proposed solution blocks the attack after its detection. The efficiency of the proposed scheme is evaluated on different performance metrics like congestion window and TCP Good put as the attack mainly targets the congestion control mechanism of TCP. � 2012 IEEE.Book chapter
