Abstract(in English) The spread of a smart phone makes the traffic capacity stringent of mobile communications. One way of solving the problem of traffic capacity is the use of a public Wi-Fi LAN. The majority of public Wi-Fi LANs are used WEP (Wired Equivalent Privacy) as a cipher. Nevertheless, the method of deciphering WEP has afready been clarified. Some deciphering programs can execute deciphering of WEP in several seconds. Especially, the communications of a smart phone treats the private information mean that increasing the cipher strength is important. To solve this problem, the improved WEP has been proposed. The features of the improved WEP are a compatible algorithm with WEP and strengthening of cipher strength. In this paper, the improved WEP is implemented on a FPGA. Then, the number of elements and registers of the improved WEP is compared with that of WEP. As a result, it is clarified that it hardly increases.
