Embodiment Construction

[0016] The method proposed by the present invention mainly realizes two-way identity authentication and key exchange between communication subjects in narrowband Internet of Things environments such as NB-IoT, and the communication subjects involved in the method include a terminal (TE) and a server (Sever). Among them: the terminal is mainly responsible for functions such as terminal information collection and processing; the server is mainly responsible for functions such as terminal access and terminal data aggregation and processing. Before the communication is established, the root key needs to be shared between the terminal and the server. Based on the symmetric cryptosystem, the "challenge-response (CR)" interaction mechanism is used to realize two-way authentication, and no third party is required to participate in the authentication process. The two-way authentication mechanism of the system is as follows: figure 1 shown.

[0017] During the authentication process, t...

Abstract

The invention discloses a lightweight security authentication and key exchange method for narrow-band internet of things. The communication main body comprises a terminal and a server. Before the communication is established, the root key is shared between the terminal and the server, and the two-way authentication is realized by adopting a challenge-response interaction mechanism based on a symmetric cryptosystem. The present invention mainly solves the problem of the two-way identity authentication and key exchange between the terminal and server in the Internet of Things application systembased on NB-IoT and other narrow-band Internet of Things connection technologies, can realize lightweight security authentication algorithm, protocol and key agreement mechanism, and meet the design requirements of low power consumption, low bandwidth consumption, low interaction frequency and high security.

Description

technical field [0001] The invention relates to a lightweight security authentication and key exchange method for narrowband Internet of Things. Background technique [0002] In September 2016, the narrowband cellular Internet of Things NB-IoT became the official standard of 3GPP R13 and was frozen and released, marking that the large-scale commercial use of the Internet of Things has entered a substantive stage. As of April 2018, there are 50 NB-IoT commercial networks in the world. In addition, related companies in the telecom industry chain around telecom operators have established various cooperation and alliances to jointly promote the industrial application of NB-IoT in all aspects of chips, modules, terminals, networks, and applications. At present, vertical industry applications in many provinces and cities in China have been gradually launched, such as smart water meters, smart gas meters, shared bicycles, smart parking lots, etc., while the promotion of industry a...
