Abstract (in Japanese) (See Japanese page) 
(in English) We propose the countermeasure technique to prevent key decipher, and improve the key-exchange protocol of IEEE 802.11 Wireless LAN. In Wireless LAN, WPA/WPA2-PSK is widly used although attackers can decipher the encryption key by capturing the process of the key generation. Our technique improves 4-way handshake that is the key generation process in Wireless LAN. Now we can generate sectret key about 2000 times rster than conventional approatch. In addition, we conbine bit strings made by recieved singnal strength and pre-shared key information to generate the encryption key. Then the encrypition key acquires tolerability to RF jamming.
