Dependability of Embedded Systems in the Industrial Internet of Things: Information Security and Reliability of the Communication Cluster

The article investigates the issue of ensuring security and confidentiality of information exchange in communication clusters of IIoT systems. The authors of the article note that existing security methods such as encryption, signatures, and authentication may be insufficient for effectively protecting against external intrusions and malicious access to data circulating within such a system. A new approach to creating resilient communication clusters is proposed, based on a combination of information exchange security and redundant hashing to localize external intrusions in industrial IoT. The authors explore various hashing techniques, their impact on system performance and security, and propose an optimal algorithm to achieve the highest level of protection. The article also examines potential security threats in communication clusters and provides practical recommendations for ensuring stability and security of information exchange. The authors highlight the advantages of the proposed approach and offer essential recommendations for its implementation. The research findings can be utilized to enhance security across a wide range of applications where security and reliability are critical aspects, including cloud systems, mobile applications, and other contemporary data exchange technologies.
