Embodiments of the present invention provide an MTC device authentication method, an MTC gateway, and a related device, which are used to solve a problem that direct interaction between a large quantity of MTC devices and a network side brings a heavy load to a network when the MTC devices are authenticated in the prior art. The method includes: performing, by an MTC gateway, mutual authentication with a core network node; performing, by the MTC gateway, mutual authentication with an MTC device; reporting, by the MTC gateway, a result of the mutual authentication with the MTC device to the core network node; and providing, by the MTC gateway, a non access stratum link protection key K between the MTC device and the core network node according to a key K1 or a key K2. According to the present invention, a link load of the network side is reduced, and an access stratum function between the MTC device and an RAN node is implemented through an MTC gateway, and the MTC device only implements a non access stratum function with the core network node, which also reduces the cost of the MTC device. |
