Abstract

An embodiment of the invention provides a non-access layer safe algorithm processing method, an access layer safe algorithm processing method and equipment thereof. The access layer safe algorithm processing method comprises the steps of: determining a home area of user equipment UE by a mobility management entity MME according to an identification of the UE; and determining an available encryption algorithm and / or an integrity protecting algorithm of the UE according to the home area of the UE and safety capability information of the UE. The non-access layer safe algorithm processing method, the access layer safe algorithm processing method and the equipment provided by the embodiment of the invention can provide a safe protecting mechanism for the user equipment.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a non-access layer and access layer security algorithm processing method and device. Background technique [0002] In communication systems, data security is realized based on algorithms, and various algorithms can provide confidentiality and integrity protection for data. [0003] The algorithms recognized by the 3rd Generation Partnership Project (3GPP for short) mainly include three types, which are the advanced encryption standard (AES) algorithm, the SNOW3G algorithm, and the Zu Chongzhi algorithm (ZUC). The ZUC algorithm is an optional algorithm. [0004] However, in the prior art, since the encryption algorithm and the integrity protection algorithm supported by the user equipment (User Equipment, referred to as UE) are quite different, especially some UEs do not support the preset security algorithm, resulting in a Mobility Management Entity (Mo...
