ABSTRACT:
In response to reception of a first piece of security code generating information from a wireless terminal by directional wireless communication, a wireless station sends wireless station ID information and a second piece of security code generating information to the wireless terminal by the directional wireless communication. The wireless station encrypts one of the first and the second pieces of security code generating information with the other of the first and the second pieces of security code generating information as an encryption key to generate a security code. The wireless terminal receives both the wireless station ID information and the second piece of security code generating information sent by directional wireless communication, and encrypts one of the first and the second pieces of security code generating information with the other of the first and the second pieces of security code generating information as the encryption key to generate the security code.This arrangement of the invention enables the user to explicitly specify a desired access point as a connection target and ensures easy and high-security connection authentication between the user's wireless terminal and the access point.
