Embodiment Construction

[0144] In order to facilitate understanding of the solution, the network architecture to which the solution of the embodiment of the present application may be applied is firstly introduced below with reference to related drawings. Such as figure 1 As shown, the future mobile communication network architecture includes a terminal device 110 , an access network node 120 and a user plane node 130 . Wherein, the terminal device 110 accesses the operation network through the access network node 120 , so as to implement communication with the user plane node 130 .

[0145] The terminal device 110 is a logical entity, and specifically may be any one of a user equipment (User Equipment), a communication device (Communication Device), and an Internet of Things (Internet of Things, IoT) device. Wherein, the user equipment may be a smart phone (smart phone), a smart watch (smart watch), a smart tablet and so on. The communication device may be a server, a gateway (Gateway, GW), a base...

Abstract

The embodiment of the invention discloses a security realization method, equipment and a system. The method comprises the steps that first equipment obtains a security policy and at least one key of asession; and the first equipment sends protection data to second equipment, wherein the protection data is obtained by protecting security of session data of the session through unitization of the atleast key according to the security policy of the session, and the second equipment is used for restoring the protection data through utilization of the at least one key according to the security policy, thereby obtaining the session data, when the first equipment is terminal equipment, the second equipment is an access network node or a user plane node, and when the first equipment is the accessnetwork node or the user plane node, the second equipment is the terminal equipment.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for implementing security. Background technique [0002] In the existing network security architecture, data security protection adopts a hop-by-hop approach, that is, security protection is performed in segments. Taking the transmission link of data from terminal device-base station-serving gateway-PDN gateway as an example, a security protection is performed between the terminal device-base station, a security protection is performed between the base station-serving gateway, and a security protection is performed between the serving gateway-PDN gateway. Perform a security protection at a time. It can be seen that in the process of data transmission, if there is a problem with the intermediate node, it may lead to data leakage. Moreover, encrypting and restoring data multiple times during data transmission will also lead to waste of resources. Co...
