A distributed authorization management method in the context of the Internet of Things

Abstract

The invention discloses a distributed authorization management method under the scene of the internet of things, which adopts the block chain technology to realize the distributed right granting process. Taking advantage of the immutability of block chains, to implement resource authorization information, public audit of important information such as authorization and power transfer information, In addition, there are many users in Internet of Things applications, resource device high accessfeature, to free the device owner from the authorization process, the function of proxy authorization and revoking proxy authorization is designed, the addition of these two features is more in line with the usage scenario of the Internet of Things application, The invention adopts the block chain technology to realize the authorization of the resource service, thoroughly solves the problem of single point failure, and all the information stored on the block chain is open and transparent, the authority transfer process is recorded on the block chain, and all links of the authorization are supervised and controlled by the whole network node.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things authorization management, and in particular relates to a distributed authorization management method in the Internet of Things scene. Background technique [0002] A typical IoT system generally has three layers: device layer, platform layer, and application layer. In a three-layer IoT system, device resource information is generally stored in the IoT platform system. When an application needs to use resource services, the The IoT platform provides service access interfaces to applications. When the IoT platform provides a resource service interface for the application platform, it first needs to determine that the resource owner allows the application to use the resource service, that is, to complete the resource authorization. [0003] Currently the most popular solution is the oauth authorization protocol. In this protocol, there are four roles: resource owner, resource server, clie...
