Problems solved by technology

At this time, if the existing security mechanism is still used and the eNB maintains a master key, then the network element on the RAN side is attacked, which may cause the master key maintained by the eNB to be cracked, which may threaten the security of other network slices sex

Abstract

The invention discloses a method for secure data transmission, an access network, a terminal and a core network device. The method comprises the following steps that: a first access network device receives a request message sent by a terminal device, sends one or more pieces of network slice selection information to a first core network device, receives a response message sent by the first core network device, sends user-plane security information to the terminal device, receives the encrypted data transmitted by the terminal device, and transmits the encrypted data to the first core network device. The user-plane security information configured by the first core network device for the terminal device is sent to the terminal device via the first access network device, so that the terminaldevice performs encryption during data transmission according to the user-plane security information, thereby improving the security and reliability during the data transmission process under a network architecture of network slices. Since the first core network device configures the user-plane security information according to one or more pieces of network slice selection information, the flexibility and security of data encryption are improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for secure data transmission, access network, terminal and core network equipment. Background technique [0002] The fifth generation mobile communication system (the fifth generation, 5G) proposed the network architecture of network slice (network slice, NS), software defined network (software defined network, SDN) and network function virtualization (network The function virtualization (NFV) technology is the core technology of the network slicing architecture. The NFV technology realizes the virtualization of the underlying physical resources and loads the virtual network function (network function, NF) to the general platform. Like virtual machines, SDN technology realizes the logical connection between virtual machines and builds a path for carrying signaling and data flow. Through the dynamic connection between the NFs of the access network (radio a...
