Embodiment Construction

[0146] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0147] One of the core concepts of the embodiment of the present application is that the terminal generates a shared key with the BSF through AKA. The shared key is used to establish a secure channel between the terminal, the operator's network, and the application server. The application server sends the authentication between the application layer and the terminal and the encryption key to the terminal through OTA.

[0148] In the following, the communication process between the terminal and the server is firstly introduced from the perspective of the server.

[0149] refer to figure 1 , which shows a flow chart of the steps of Embodiment 1 of a communication method between a terminal and a server of...

Abstract

The embodiment of the invention provides a communication method and device for a terminal and a server. The communication method comprises the steps that a first server receives a first request message sent by the terminal, and the first request message is used for enabling the first server to send an authentication request to a second server, and obtaining a first secret key from the second server; the first server sends a first request response message corresponding to the first request message to a terminal, wherein the first request response message comprises a second key; the first serverreceives a second request message sent by the terminal, and the second request message comprises a second key identifier, and the second key identifier is used for enabling the first server to generate a second request response message corresponding to the second request message according to a second key corresponding to the second key identifier; and the first server sends a second request response message to the terminal. The terminal obtains the authentication and the secret key from the server through over-the-air downloading, so that the generation and the use of the secret key are moreflexible.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a communication method between a terminal and a server, and a communication device between a terminal and a server. Background technique [0002] The Internet of Things technology is the third information technology revolution after computers and the Internet. It has the characteristics of real-time and interactivity, and has been widely used in many fields such as urban management, digital home, positioning and navigation, logistics management, and security systems. The topic of IoT security is becoming more and more important. IoT devices need to communicate with application servers through a set of security mechanisms to ensure the security of services and user privacy data. [0003] In order to solve the authentication between the application server and the Internet of Things device and the establishment of a secure channel, 3GPP (Third Generation Mob...
