Patent ID: 7409550

Claim:
A method for binding devices connected by a wireless network, comprising: setting a first timeout in a master device; performing a key exchange between the master device and a slave device; terminating the key exchange if the first timeout expires and the key exchange is incomplete; setting a second timeout in the master device and a third timeout in the slave device if the key exchange is complete, in which the first timeout is less than the third timeout and the third timeout is less than the second timeout; establishing a binding to the slave device in the master device if the master device receives a response from the slave device after the second time expires, and otherwise disabling the slave device; and establishing a binding to the master device in the slave device if the third timeout expires and there is only one key exchange detected by the slave device, and otherwise blocking further operation of the slave device by the slave device if there more than one key exchange is detected by the slave device.
