摘要: 僵尸网络结构的不断改进对网络安全造成了极大的威胁,如何深入研究其结构本身的固有性质对抵御该种攻击方式显得尤为重要。从复杂网络的角度模拟非结构化P2P僵尸网络,通过定义度量标准并应用网络中心化指标分析非结构化P2P僵尸网络面对节点失效时的鲁棒性。实验结果表明,非结构化P2P僵尸网络在面对随机节点失效时其鲁棒性较强,而面对高中心化节点失效时其鲁棒性将会迅速降低。

Abstract: Constant improvement of botnet structure has caused great threat to network security, so it is very important to study the inherent characteristics of botnet structure to defense this kind of attack. This paper simulated the unstructured P2P botnet from the perspective of complex network, then proposed metrics and applied the theory of complex centrality to analyze the robustness of the unstructured P2P botnet when it encountered nodes failure. The experimental results demonstrate that the unstructured P2P botnet displays high robustness when it encounters random nodes failure, but its robustness drops quickly when it encounters central nodes failure.

Key words: unstructured P2P botnet, complex network, centrality of network, node failure, robustness
