Abstract:

In order to eliminate the attack in a quick mode and ensure the safety of communication software servers without too much overhead on routers, with a three layer framework, a traceback approach with probabilistic packet marking Internet protocol is proposed based on cooperations, called cooperation based probabilistic packet marking (CPPM). The proposed algorithm adjusts the marking probability and marking information transmission fashion according to the load of routers in the network. It can reconstruct the attack path back to the intrusion source in a quick mode with less impact on the network. Simulations show the effectiveness and practicability of the algorithm.
