Patent ID: 7467302

Claim:
A secure connection mechanism capable of automatically negotiating password between wireless client terminal and wireless access terminal, wherein the secure connection mechanism is established between at least one wireless client terminal and at least one wireless access terminal, wherein the wireless client terminal is provided with an application software, a control button and an output device, such that when the wireless client terminal is actuated and the control button is triggered, the following steps are performed so as to enable the secure connection mechanism: the output device prompts to instruct user to turn a switch button on the wireless access terminal to a secure connection mode; an encryption/decryption mechanism connects the wireless client terminal to the wireless access terminal with automatically negotiating a connection password within a predetermined period in a wireless communication way after being in the secure connection mode; wherein the secure connection mechanism further comprising: the wireless client terminal produces a first public key for encryption and a first private key from for decryption; a second public key and a second private key are assigned to the wireless access terminal, wherein the second private key is stored in the wireless access terminal, and the second public key is stored in the wireless client terminal; the wireless client terminal uses the second public key to encrypt the first public key and adds the encrypted first public key into a request joint packet, which is transmitted to the wireless access terminal; the wireless access terminal uses the second private key to decrypt the encrypted first public key; the wireless access terminal uses the first public key to encrypt a password, which is then transmitted back to the wireless client terminal though an confirmation packet; the wireless client terminal utilizes the first private key to decrypt the encrypted password for obtaining the password required for the wireless LAN secure connection.
