Abstract

Provided are a non-access layer and access layer security algorithm processing method and device. The access layer security algorithm processing method comprises: according to an identifier of a user equipment (UE), a mobility management entity (MME) determining an attribution area of the UE; and the MME judging an encryption algorithm and / or an integrity protection algorithm available to the UE according to the attribution area of the UE and security capability information about the UE. The provided non-access layer and access layer security algorithm processing method and device can provide a safe protection 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, the Mobility Management Entity (Mobility Mana...
