Abstract
A secure communications method includes: receiving, by a first network device, a second ephemeral public key of a second network device; determining, by the first network device, an ephemeral session key based on a first shared key, a first ephemeral secret key of the first network device, and the second ephemeral public key, where the first shared key is shared between the first network device and the second network device; and performing, by the first network device, secure communication with the second network device based on the ephemeral session key.
