Abstract

The present invention proposes an over-the-air certification method and system based on NB-IoT communication modules. The present invention aims at NB-IoT terminals using NB-IoT network communication, adopts the Internet of Things general protocol LWM2M+COAP, and combines the Internet of Things The cloud platform bootstrap service builds a transmission channel to connect with the security authentication management system, and issues digital certificates for NB-IoT terminals. The NB-IoT terminal applying for the certificate and the security authentication management system of the IoT cloud platform perform mutual identity authentication, and based on asymmetric encryption The key secure data transmission link realizes the encryption and protection of the certification request data transmitted over the network, and simplifies the certification receipt data to reduce network overhead and completes integrity protection. Compared with the traditional offline certificate issuance method, the air certificate issuance method of the present invention can automatically complete the certificate application and issuance process, thereby effectively saving labor costs and time costs in the production process.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to an over-the-air certification method and system based on an NB-IoT communication module. Background technique [0002] In recent years, with the advent of the Internet of Everything era, more and more IoT terminals are connected to the IoT cloud platform, and NB-IoT communication methods are widely used in low-speed, wide-area network scenarios. In order to ensure that the identity of the IoT terminal connected to the IoT cloud platform through NB-IoT communication module communication is credible, it is necessary to issue a digital certificate to the NB-IoT terminal, and perform access authentication and security of the IoT cloud platform based on the digital certificate. communication. The traditional certificate issuance method has problems such as long process, complicated operation, and low execution efficiency. Contents of the invention [0003] I...
