Abstract
Embodiments of the present invention provide a security authentication method, apparatus, and system, where the method includes: verifying a feature identifier for identifying terminal equipment, where the terminal equipment is machine-to-machine equipment; and obtaining a key corresponding to the feature identifier, so as to perform secure communication with the terminal equipment according to the key. In the embodiments of the present invention, after terminal equipment, a mobility management entity, and a home subscriber system successfully perform authentication and key agreement, it is verified whether a feature identifier of the terminal is legal, and when the feature identifier of the terminal is a legal identifier, a key is obtained according to the feature identifier, so that the mobility management entity and the terminal equipment perform secure communication according to the key, thereby implementing secure communication between M2M equipment and a network side.
