Abstract
A secure connection method for a network device includes: acquiring a public key operation value of a second device in an out-of-band manner; sending public key information of a first device to the second device; receiving public key information of the second device that is sent by the second device, and decrypting the public key information of the second device by using a private key of the first device, to obtain the public key of the second device; and performing a preset-algorithm operation on the public key of the second device to obtain a copy of the public key operation value of the second device, and after the copy of the public key operation value of the second device matches the public key operation value of the second device, accepting received connection information sent by the second device.
