The invention provides an AMF based on MEC and an identity authentication method, construction method and device thereof. The identity authentication method comprises the steps that an AMF entity receives an identity authentication request sent by at least one terminal; the AMF entity selects one terminal from the at least one terminal as a two-way authentication terminal; the AMF entity performstwo-way authentication with the bidirectional authentication terminal; the AMF entity performs one-way authentication on other terminals except the two-way authentication terminal in the at least oneterminal by using the success result of the two-way authentication, wherein the AMF entity is constructed according to the following mode: selecting edge physical infrastructure and constructing an AMF entity on the edge physical infrastructure by using network function virtualization (NFV). Conventional authentication and key agreement standards are simplified, and low-delay secure access authentication is performed on the terminals based on edge computing in the scene that the plurality of terminals authenticate the same service network at the same time, so that signaling overhead is reduced, and network congestion is avoided.
