Research and implementation of an anti-replay method based on WIA-PA network

Replay attack is one of the most common and the most dangerous attack in wireless industrious network. Most previous methods only consider the replay attack itself, not considering the security of the whole system and the energy consumption. In this paper, we introduce the third-party detection modul to monitor and analyze all the packets of the network to decide whether to use the local anti-replay attack modul. In the local anti-replay attack modul, we construct the anti-replay packets in order to use the improved anti-replay window protocol. Through filtering some serious delay packets, we can reduce the number of discarded good messages. Simulation results indicate this improved protocol is indeed increasing the detection rate of the replay packets.
