Abstract
Decentralized Cybersecurity Mesh Architecture (DCSMA) is a new cybersecurity architecture designed to secure distributed networks, particularly Internet of Things (IoT) environments. Unlike traditional approaches that rely on centralized control or isolated security silos, it leverages blockchain technology to enable fully decentralized security management, eliminating single points of failure and improving coordination among security components. In this paper, a practical implementation of DCSMA is presented and evaluated in an Internet of Vehicles (IoV) environment. The system is developed using a hybrid simulation framework that combines Carla for IoV scenarios and Ganache for blockchain emulation. It integrates key technologies, including Decentralized Identity (DID), Secure Multi-Party Computation (SMPC), smart contracts, and Event-Driven Architecture (EDA), to support secure communication and distributed policy enforcement. The proposed system is evaluated through multiple case studies covering data protection, communication and policy enforcement, and threat detection. Performance is analyzed using metrics such as latency, memory consumption, scalability, throughput, and transaction success rate, in addition to machine learning-based anomaly detection. The results demonstrate that the proposed implementation achieves efficient decentralized security with low overhead and effective threat detection, highlighting its suitability as a scalable and resilient cybersecurity solution for IoV and distributed IoT systems.
This study tackles security, scalability, and efficiency issues in the IoV framework by implementing a decentralized, blockchain-based authentication framework that addresses cryptographic vulnerabilities, reduces computational and communication costs, and improves real-time performance.

The smart grid systems are increasingly becoming digital where the system is taking a new direction into greater operational efficiency and real time energy management. The increased number of Internet of Things (IoT) devices and communication networks has widened the area of attack as well, thus smart grids are vulnerable to more sophisticated cyber attacks like false data injection, denial-of-data manipulation and service attacks. The traditional centralized security controls are not sufficient because of the limitation of single point failure, scalability limitations, and demand decentralized and resilient security controls. The use of blockchain technology in this regard has become a potential solution in order to improve the level of security by utilizing the transparent, decentralized, and immutable features of the technology. To provide cybersecurity approaches of smart grid systems, a taxonomical structure of blockchain technology is proposed in this paper. Besides that it shows the categorization of the various techniques into secure data management, secure energy trading, device authentication, data integrity assurance and communication protection. A detailed analysis of existing works was undertaken to determine their efficiency based on the security, scale and complexity of implementation. The results of the review describe some of the major challenges, such as latency and energy overhead and provide future research opportunities on effective smart grid security frameworks.
