摘要
P2P网络蠕虫能在短时间内破坏整个P2P网络,成为P2P应用最为严重的安全威胁。结合P2P网络蠕虫的传播特点,提出一种节点信任机制,P2P节点之间的信任度只有达到规定的阈值才能进行深度的信息交流,从而有效地遏制P2P蠕虫在网络中的快速传播,使网络反毒系统有足够的时间来发现和清除蠕虫病毒。通过仿真实验表明,这种机制对P2P网络蠕虫有良好的防治效果。
P2P worm can destroy the entire P2P network in a short time, which turns out to be the biggest security threat of P2P application. Proposes node trust mechanism that in-depth exchange of information becomes possible only when the trust between P2P nodes reaches the required threshold so that the P2P worms fast spread can be effectively curbed and the anti-virus system can have sufficient time to find and remove worm viruses. The simulation results show that this mechanism can effectively protect the network against P2P worms attack.
