| Abstract: Security problems occur when multiple different devices are continuously connected with blockchain system. Aiming at these security problems in Internet of Things (IoT), this paper proposes to design a distributed IoT information security management system based on blockchain technology. This system can access devices through identity authentication and it will control the permissions of various devices. At the same time, security arbitration mechanism is integrated into a smart contract. In terms of information management, data is classified and stored in order to ensure data security. Finally, function test is conducted to test the safety and effectiveness. Various related data is used as system input and the system output results reach the expected goals. |
