Use of Blockchain in IoT Devices Security: A Systematic Mapping Study

Abstract:

Information security in IoT devices is considered a great challenge within the field of computing, which has been growing based on the architecture and the resources that compose it. The implementation of Blockchain has provided improvements in security and reliability for handling data. However, there is no concrete information on techniques, advantages, or results of the use of Blockchain in IoT devices. To identify relevant information on the use of Blockchain in smart devices and present the results as a basis for future research, we promoted a systematic mapping study to classify the selected studies and summarize their content. A limited number of articles was evidenced according to the proposed search chain, only since 2017 an interest in the subject has been observed, the same interest that grows rapidly over time. In addition, disadvantages and shortcomings were identified when applying Blockchain in IoT. Therefore, there is a need to evaluate the performance of Blockchain in different environments and new investigations that provide better results as computer vulnerabilities and their possible effects on devices used in IoT increase.
