<p>In the cipher key setting system of the invention, the access point (20) detects the terminals (50-70) connected to the wireless LAN through the access point (20) itself repeatedly at each predetermined time, reviews the adopted cipher systems when there are replacements of the terminals (50-70) participating in the wireless LAN and a decrease in the number of the terminals, and adopts a cipher system according to the guideline 'selecting the cipher system of the highest security level among the cipher systems that the devices building up the network can commonly adopt'. Thereby, the system of the invention prevents the security setting from being maintained at a needlessly low level, after a certain terminal withdrew from the network or after some terminals were replaced. <IMAGE></p> |
