NETWORK CONFIGURATION METHOD, AND RELATED DEVICE AND SYSTEM

摘要

Embodiments of the present invention disclose a network configuration method, including: acquiring a public key operation value of a second device in an out-of-band manner, where the public key operation value of the second device is a result obtained by performing an operation of a preset algorithm on a public key that is used by the second device to perform key exchange; generating public key information of a first device according to a public key that is used by the first device to perform key exchange, and sending the public key information of the first device to the second device, so that the second device acquires the public key of the first device according to the public key information of the first device; acquiring a public key copy of the second device that is sent by the second device and that is used to perform key exchange; performing an operation of the preset algorithm on the public key copy of the second device, to obtain a public key operation value copy of the second device; and after the public key operation value copy of the second device matches the public key operation value of the second device, generating a first exchange key according to a private key that is used by the first device to perform key exchange and the acquired public key copy of the second device, so as to process configuration information between the first device and the second device by using the first exchange key. The present invention simplifies a network configuration process.
