A first electronic device transmits first configuration information of the first electronic device collected by a tamper-resistant chip mounted thereon and approved by a third-party device to a second electronic device over a short-distance network. The second electronic device transmits second configuration information of the second electronic device collected by a tamper-resistant chip mounted thereon and approved by the third-party device to the first electronic device over the short-distance network. The first electronic device transmits the first configuration information and the second configuration information to the second electronic device over a network. The second electronic device controls connection between the first electronic device and the second electronic device over the network based on the first configuration information and the second configuration information received from the first electronic device.
