Abstract
A wireless LAN device which performs wireless communication in a wireless network comprises: a communication section for performing the wireless communication such that a packet can be relayed in the wireless network; and a setting section for obtaining first identification information from another wireless LAN device present in a communicable state within a radio wave arrival range of the wireless LAN device, which first identification information can identify the other wireless LAN device, and setting a role for executing an asymmetric protocol asymmetric between the wireless LAN device and the other wireless LAN device, the role being set based on the first identification information, and second identification information, stored in the wireless LAN device, that can identify the wireless LAN device. The wireless LAN device shares an encryption key, based on the set role, and relays a packet by encrypting the packet by using the encryption key.
