Embodiment Construction

[0162] Aiming at the problems in the prior art that authentication, air interface connection establishment, and non-access layer connection establishment are carried out sequentially, and there are too many signaling interactions, resulting in a long time-consuming AKA process, and the coupling of access layer security and non-access layer security In order to reduce the coupling between the key systems of the access layer and the non-access layer and improve the efficiency of the AKA process, in the embodiment of the present application, a solution for fast AKA is provided.

[0163] In order to enable ordinary persons in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0164] refer to figure 2 As shown, in the embodiment of the present application, an AKA system is provided, and t...

Abstract

The present application discloses an AKA method and device. Aiming at the problems of many interactions and time-consuming AKA process in the prior art, the method includes: the user equipment receives the encrypted air interface security configuration information sent by the air interface node, and decrypts the acquired air interface security configuration information, and send the user identification and non-access stratum message to the non-access stratum node through the air interface node, triggering the non-access stratum node to obtain the second key and the initial non-access stratum security algorithm from the network security center , the user equipment receives the encrypted response message sent by the non-access stratum node. In this application, the processes of air interface connection establishment, authentication, and air interface security activation are performed in parallel, which reduces the signaling interaction required in the AKA process, speeds up the start-up process of user equipment, and at the same time reduces access layer and non-access Coupling between layer key systems.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to an AKA method and device. Background technique [0002] Authentication and Key Agreement (AKA) uses a challenge response mechanism to complete the identity authentication process between the user equipment and the network, and negotiates the communication encryption key based on the identity authentication process. Through authentication and encryption, the security of the mobile communication network is protected. [0003] In the current communication system, take the 5G system as an example, refer to figure 1 As shown, the AKA process is as follows: [0004] Step 101 to Step 103: An RRC connection is established between a user equipment (User Equipment, UE) and a 5G base station (next generationNode B, gNB). [0005] Step 104: The UE transmits a non-access stratum message to the AMF, and the non-access stratum message carries a user identifier. [000...
