Abstract

The embodiment of the present application provides a method and device for sending a message, in which a request message is sent to a terminal device through a security gateway, and the terminal device obtains the security context between the terminal device and the security gateway according to the security parameters of the security gateway and the security parameters of the terminal device , using the security context to protect the sent message, thereby improving the security of the sent message.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for sending messages. Background technique [0002] For untrusted (Untrusted) non-third generation partnership project (3rd generation partnership project, 3GPP) access network scenarios, in the 4G network architecture, the terminal device performs access authentication before sending a message, and the terminal device In the authorization process, the access network is accessed through the wireless local area network (Wireless Local Area Networks, WLAN), and the WLAN initiates a verification request to the verification, authorization and account server (Authentication, Authorization, Accounting Server, AAA Server) The terminal device obtains its own Internet Protocol (Internet Protocol, IP) address, and then uses the IP address to perform tunnel authentication, thereby ensuring secure transmission of messages. [0003] In the 5G network ...
