蠕虫软件仿真技术研究与进展

蠕虫传播特性研究已经成为蠕虫研究的重要内容。首先从仿真规模和准确度两个方面衡量了现有各种蠕虫传播特性研究技术，并指出软件仿真技术的优势所在。然后从网络建模和蠕虫建模两个方面对蠕虫软件仿真技术做了分析，接着按照网络建模方式将现有系统分为高度抽象的软件仿真系统、数据包级的软件仿真系统和大规模分布式软件仿真系统。最后给出了网络蠕虫软件仿真研究的趋势与展望。该研究能够为蠕虫研究者蠕虫设计软件仿真系统和有效的蠕虫检测和防御机制提供指导。

Research and Development of Internet Worm Simulation

Worm propagation characteristics research has become an important aspect of the worm research works. In this paper the ahernativcs for worm propagation were firstly measured from both scalability and fidelity, and the advantages of simulation were pointed out. Then worm simulation technology is analyzed from both Internet modeling and worm modeling views, Afterwards the existing simulation systems are classified into three types, which are high - abstracted simulation systems, packet - level simulation systems and large scale distributed simulation systems. Research trends and prediction in this area are also addressed at last. This research work will provide a guide for designing both simulation systems and effective worm detecting and defending methods.
