Abstract

The present application discloses a communication method and device, wherein the method includes: a terminal device receives a first authentication request from a safety function network element; the terminal device obtains authentication reference information according to the first authentication request, and the authentication reference The information is a response value or a resynchronization identifier or a cause indication value; the terminal device sends an authentication response message to the security function network element, and the authentication response message includes a first information element for carrying the response value, for carrying The second information element of the resynchronization identifier and the third information element used to carry a cause indication value, the authentication reference information is carried in the information element corresponding to the authentication reference information.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] At present, pseudo-base station technology poses a great threat to the security of communication systems. For example, pseudo-base stations can obtain the identity of a terminal device, which can be an International Mobile Subscriber Identification Number (IMSI). Further, the fake base station may also attack the terminal device according to its identity, for example, track the location of the terminal device, thereby causing privacy leakage of the user of the terminal device. [0003] For example, the fake base station may use the obtained IMSI to apply for an authentication vector (Authentication Vector, AV) from the core network, generate an authentication request according to the authentication vector, and send the authentication request to the terminal device. If the terminal device is a te...
