Abstract

The invention provides a method and device for protecting positioning auxiliary information. The method comprises the following steps: 1, preparing raw materials; the AMF receives a tracking area identifier used for indicating a tracking area to which the first terminal belongs, allocating a first key to the first terminal according to the tracking area to which the first terminal belongs, compared with a traditional scheme in which a mobile management network element allocates a unified key to all manageable terminals, the embodiment of the invention can allocate an appropriate key to the first terminal and protect the auxiliary information of the first terminal through the key, thereby improving the safety performance of the auxiliary information.
