PROBLEM TO BE SOLVED: To provide a method for setting an encryption key by simple work while assuring advanced security. SOLUTION: A wireless router 2 generates a public key 1 and a private key 1. Upon receiving a setting request packet from a wireless adapter 3, the public key 1 is transmitted. In response to an acknowledgement from a single wireless router 2, the wireless adapter 3 sends back its own inherent information and the information obtained by encrypting the inherent information using the public key 1. The wireless router 2 decrypts the encrypted information and authenticates its wireless adapter 3, if the decrypted information agrees with the received intrinsic information. The authenticated wireless adapter 3 generates a WEP key in a random manner and encrypts it with the public key 1, before being transmitted to the wireless router 2. That WEP key is set in the wireless router 2 and in the wireless adapter 3. COPYRIGHT: (C)2007,JPO&INPIT |
