With the rapid development of information technology, the Internet security problem is becoming increasing severe. DDos has become a tremendously harmful internet attack method because of its many characterisitics such as easy to implement. In this paper we try to track DDoS attack source with more effective means.By applying Fast Fixed-point Algorithm for Independent Component Analysis(FastICA) which is widely exercised in digital signal processing recently to the field of network security and combining DDoS source track technology based on flow model matchingthis essay has put forward a new traceback method of DDoS attack utilizing analysis of traffic models based on fast ICA. Simulation experiment, verification and research has also been carried out to test the practical efficiency of this method. Source
