A Blockchain-Based Mobile IOT Network Interconnection Security Trusted Protocol Model

With the continuous development of information technology and internet of things, technology of the mobile Internet of Things (mobile IOT) has been widely used in medical and health, smart home, transportation, logistics and other industries. At the same time, the network security issues of mobile IOT have become increasingly prominent. What's more serious is that the destructive power of these cyber threats has grown geometrically by taking the advantage of cloud computing and big data. This threat can be summarized as a non-trusted model threat under a "centralized" network architecture. By analyzing such security threats through real-world cases, this paper proposes a model to solve such security problems. Firstly, a variety of smart home and intelligent voice-controlled robots in the market are selected as research objects, and then the Man-in-the-Middle Attacks such as intelligence mining and data packet hijacking are used to detect the security vulnerabilities of such mobile IOT schemes. Through illustrating the huge network security threat faced by mobile IOT under the new situation, the example summarizes the current security risks in such mobile IOT solutions, and propose a secure and trusted mobile IOT network interconnection security model based on blockchain technology to remedy this problem.
