Problems solved by technology

[0004] The problem to be solved by the present invention is that plaintext communication is vulnerable to illegal operations such as data hijacking, data tampering, and control replay by attackers, while existing ciphertext communication uses a fixed key for data encryption, which is easily reversed by the attacker to obtain a fixed key. key

Embodiment Construction

[0040] In order to make the above objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] Please refer to Figure 1-3 As shown, the security communication control method of the Internet of Things based on NB-IoT (Narrowband Internet of Things) of the present invention specifically includes:

[0042] S1, server (cloud) pre-generates data; Concretely, pre-generate data by the DNS life cycle system of described server, described pre-generate data comprises MAC address, module hardware number, module public key, module private key, Factory public key.

[0043] S2. The module (equipment) determines the tooling data according to the pre-generated data; as the premise of the key negotiation between the module and the server, a series of data needs to be loaded into the module through the production line before leaving th...

Abstract

The present invention provides a NB‑IoT-based secure communication control method for the Internet of Things, including: the server pre-generates data; the module determines the tooling data according to the pre-generated data; the module and the server use the pre-generated data and the tooling data Perform key agreement. The NB‑IoT-based secure communication control method for the Internet of Things of the present invention can effectively avoid plaintext transmission and prevent key guessing, data tampering and replay attacks.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method for controlling secure communication of the Internet of Things based on NB-IoT. Background technique [0002] At present, IoT devices based on NB-IoT communication modules on the market, due to the limitation of memory and flash resources, their communication methods are mostly plaintext, or business data is encrypted with a fixed key. However, plaintext communication is vulnerable to illegal operations such as data hijacking, data tampering, and control replay by attackers. [0003] If the data is encrypted with a fixed key, the attacker can still deduce the fixed key after collecting a large amount of data, and the subsequent ciphertext transmission is actually the same as the plaintext transmission. SUMMARY OF THE INVENTION [0004] The problem to be solved by the present invention is that plaintext communication is vulnerable to illegal opera...
