Abstract

The present invention discloses an information interaction method, a home network, a user terminal, and an information interaction system, and relates to the field of information communication technology. The information interaction method comprises: a home network authentication network element performs a security algorithm negotiation with user equipment in a user equipment access authenticationprocess; the home network authentication network element sends a negotiated security algorithm to a home network information receiving and transmitting network element; and during an information interaction process between the home network information receiving and transmitting network element and the user equipment, the negotiated security algorithm is adopted to carry out a security process onthe interaction information. The method can implement security protection for the information interaction between the home network and the user equipment without increasing communication flow.

Description

technical field [0001] The present invention relates to the technical field of information communication, in particular to an information interaction method, a home network, a user terminal and an information interaction system. Background technique [0002] As the fifth-generation mobile communication network, 5G network has a theoretical maximum transmission speed of tens of Gb per second, which is hundreds of times faster than that of 4G network. The main goal of 5G networks is to keep end users always connected. The 5G network will be a true upgrade of the 4G network, and its basic requirements are different from today's wireless network. [0003] The security architecture of the current 5G network designed by 3GPP basically only inherits the functions of the 4G network, only supports the security protection of information and data between the visited network and the UE, and does not support the information exchange between the home network and the UE. safety protectio...
