Abstract: An Internet of Things (IoT)-based thing management system using block chain authentication, where unit nodes connect to each other through a network, things connect to each other in each of the unit nodes, and control instructions for causing the things to operate are mutually authenticated by the unit nodes. Each of the things performing individual functions separately, and a core which includes n block chain having n blocks recording operation histories of the things thereon. The core generating public and private keys based on the n block chain and providing the keys to each of the things, wherein one of the things includes a controller which has a list of public keys provided by the core. The controller sends a control instruction so as to control operations of the thing. The thing sends the controller a response signal and performs an operation according to the control instruction.

Abstract: An Internet of Things (IoT)-based thing management system using block chain authentication wherein unit nodes connect to each other through a wire and/or wireless communication network, things connect to each other in each of the unit nodes, and control instructions for causing the things to operate are mutually authenticated by the unit nodes to confirm the validity of the instructions; each of the unit nodes includes: a plurality of things which connect to the wire and/or wireless communication network, each of the things performing individual functions separately; and a core which includes n block chain having n blocks recording operation histories of the things thereon, the blocks being linked one after another in the form of a chain, and the core generating public keys and private keys based on the n block chain and providing the generated keys to each of the things, wherein one of the things includes a controller which has a list of public keys provided by the core, each of the public keys is unique to
