Trace malicious source to guarantee cyber security for mass monitor critical infrastructure.

The proposed traceback scheme does not take into account the trust of node which leads to the low effectiveness. A trust-aware probability marking (TAPM) traceback scheme is proposed to locate malicious source quickly. In TAPM scheme, the node is marked with difference marking probability according to its trust which is deduced by trust evaluation. The high marking probability for low trust node can locate malicious source quickly, and the low marking probability for high trust node can reduce the number of marking to improve the network lifetime, so the security and the network lifetime can be improved in TAPM scheme.
