Functional analysis of the use of blockchain technology in the internet of things (IoT) Free

The Internet of Things is a system of interconnection of devices ("things") for data collection, as well as smart decision-making. The flow of information from these built-in sensors, software and other technologies circulates over the Internet. Most IoT platforms have two main features: publishing and subscribing. This IoT data transmission model requires a connection between devices and servers. The model requires a central broker, a program module and a working server to collect and arrange messages according to the topics. This is where the IoT vulnerability is, as there are no internal security measures to protect both data and access to terminal equipment. The security provided by blockchain technology can solve the main security flaws of IoT. Blockchain capabilities such as immutability, transparency, data encryption, operational resilience to almost all widely used hacking attacks could solve these IoT architectural vulnerabilities. The article will look at an overview functional analysis of existing IoT messaging models, parallel to the main types of hacking attacks. The structural analysis of the blockchain consensus used will highlight the technology’s ability to address IoT’s architectural shortcomings.
