Secure login method for establishing a wireless local area network connection, and wireless local area network system

摘要

A secure login method for a wireless local area network is implemented using a first wireless terminal that has already been logged in to the wireless local area network and that has obtained a settings value, and a second wireless terminal that has yet to be logged in to the wireless local area network and that has a public key and a secret key conforming to an asymmetric public key technique. The method includes: (A) enabling the second wireless terminal to send the public key to the first wireless terminal; (B) enabling the first wireless terminal to encrypt the settings value into an encrypted text using the public key and to send the encrypted text to the second wireless terminal; and (C) enabling the second wireless terminal to decrypt the encrypted text using the secret key so as to recover the original settings value that serves as a basis for logging in to the wireless local area network.
