Application of primary components analysis of security threat in wireless network

Internet Security mechanism of itself is more vulnerable. While coupled with the inherent openness of wireless network media and the limitations of mobile storage and computing resources in the wireless network environment, it does not only have to be encountered with the security threats in the cable network environment but also the emerging wireless-specific threats to the wireless environment. Under the premise of minimizing the information loss of data, the application of the primary components analysis (PCA) in the investigation on security threat in wireless network approved to be practicable. Through linear variation and abandoning a bit of information, PCA can be perfectly divided from the reasons of security threat in wireless network.
