IoT device management method based on block chain technology

Abstract

The invention discloses an IoT device management method based on a block chain technology. The method comprises the following steps that: S1, each device generates a pair of public and private keys to create an identity, the private key is safely managed by each device, and the public key is used for identifying the unique and verifiable identity of the device in a block chain; S2, each device dynamically creates an identity group according to needs, a plurality of devices with verified identities can be added into the group, and each device can also join in a plurality of identity groups; S3, after a device joins in a certain group, the group initiator uses the private key of the group initiator to sign the certificate of the device and uploads the certificate to a block chain; S4, each identity group has a specific encryption key; and S5, an encrypted device management instruction is recorded and issued by using the auditing performance. According to the method, a command is stored in the devices by using the block chain and is ensured to be authorized through encryption, a private network is not needed any more, and an existing public network infrastructure is used for device management.

Description

technical field [0001] The present invention belongs to the field of IoT device management, and more specifically relates to an IoT device management method based on block chain technology. Background technique [0002] With the vigorous development of enterprise-level IT infrastructure, the number of devices is increasing day by day, and they are gradually scattered in different geographical locations, which brings new challenges to traditional device management solutions. The traditional method of managing devices is through a centralized The management of a large number of IoT devices is managed and controlled through a single data center. However, such a distributed cloud platform still cannot fundamentally solve the scalability problem of centralized management. As the number of devices increases and reaches a certain critical point , it is unrealistic to use a centralized management tool to manage each device, and the traditional centralized management device solution ...

[0002] With the vigorous development of enterprise-level IT infrastructure, the number of devices is increasing day by day, and they are gradually scattered in different geographical locations, which brings new challenges to traditional device management solutions. The traditional method of managing devices is through a centralized The management of a large number of IoT devices is managed and controlled through a single data center. However, such a distributed cloud platform still cannot fundamentally solve the scalability problem of centralized management. As the number of devices increases and reaches a certain critical point , it is unrealistic to use a centralized management tool to manage each device, and the traditional centralized management device solution has no ability to manage these geographically dispersed and numerous IoT devices due to various limitations. Therefore, we propose A blockchain technology-based IoT device management method
