Designing a Secure IoT Network by Using Blockchain
MetadataShow full item record
By the emergence of many intelligent application areas that can be diversified, such as homes and cities being smarter, creates new opportunities. It is clear that the Internet of Things (IoT) will be a large network with a growing number of connected devices at as a logarithmic speed in the coming years. IoT devices are embedded system elements that range from simple to complex. Typically, these IoT devices are more vulnerable to attack than other IoT endpoint devices, such as smartphones, tablets, computers, or servers, because they are limited in processing, storing, and networking capacity for information. Blockchain is a distributed, encrypted, immutable, and low-tolerance distributed ledger application. It is increasingly used in areas where data security is important. In this study, it is aimed to use IoT devices as blockchain elements as a solution to existing IoT security problems. A blockchain network was created by using Raspberry Pi 3 elements. © 2019 IEEE.
