Abstract
A key configuration method includes acquiring, by a first device, a public key of a second device through a secure medium; sending, by the first device, information used for obtaining a shared key to the second device; and obtaining, by the second device, a shared key using a private key of the second device and the information that is used for obtaining a shared key. The first device obtains the shared key using the information used for obtaining a shared key or using a private key of the first device. The present disclosure ensures that the public key of the second device reaches the first device, avoids that an attacker masquerades as the second device to establish a secure connection with the first device, so that the attacker cannot listen to a message between the first device and the second device.
