摘要

A data transmission method includes calculating, by a user equipment (UE), a first message authentication code of first location privacy setting data, sending, by the UE, the first message authentication code and the first location privacy setting data to a data management network element, receiving, by the UE, a second message authentication code from the data management network element, calculating, by the UE, a third message authentication code of the first location privacy setting data, determining, by the UE, that the first location privacy setting data is not tampered with when the second message authentication code is the same as the third message authentication code.

說明書

An example in which this embodiment of this application is applied to the schematic diagram of the network architecture shown in FIG. 4 is used. FIG. 6A and FIG. 6B are a schematic flowchart of a data transmission method according to Embodiment 1 of this application. In this embodiment, UE performs digital signing on location privacy setting data, to effectively prevent the location privacy setting data from being tampered with, thereby ensuring end-to-end integrity protection of location privacy setting data between the UE and a UDM. The embodiment shown in FIG. 6A and FIG. 6B may include but are not limited to the following steps.

Step S201: UE performs digital signing on first location privacy setting data, to obtain a first digital signature.

The first location privacy setting data is first location privacy setting data entered or updated by a user on the UE, and is first location privacy setting data before digital signing processing is performed. The first digital signature is obtained by performing digital signing by the UE on the first location privacy setting data.
