FPGA Implementation of Winny Packets Detection for Mobile Computing

IPS is crucial for Internet community. Especially, it is true for mobile computing due to its diversity. Since IPS has been developed in the form of software, it has problems of CPU resources, processing speed, and failure risk due to interference with applications. Thus, they cannot be installed in mobile platforms. In order to overcome the shortcoming of software IPS, we have so far exploited a hardware-and host-based IPS or H-HIPS. We focus in this paper the implementation of Winny packets detection unit in H-HIPS considering its importance. Although Winny is a useful file exchanging software, it is also a cause of information leakage. This is serious in view of especially corporation, government, and academic. Firstly, we exploit a detection algorithm. Then, it is implemented in FPGA. This is compared with regular software IPS. Although FPGA is slower than PC used in running IPS, it is 300 times higher.
