| Résumé : |
Managing security keys for large, dynamic Internet of Things (IoT) networks is
a significant challenge, often leading to security gaps and high operational costs. To
address this, this project involved the design and implementation of a centralized webbased
platform to simplify and automate this complex process. The platform is built
upon a lightweight cryptographic method known as the Efficient Vectors-Based Key
Management Scheme (EVKMS), which is specifically designed for resource-constrained
devices. The system automates the entire security lifecycle of devices, including their
addition, removal, and key updates, through a robust, task-based orchestration system
managed by a modern backend server. A key contribution is the implementation of a
comprehensive, immutable audit log that automatically records every administrative
action, ensuring full traceability and accountability. The platform’s effectiveness and its
workflows were validated in a high-fidelity simulation environment that mimics realworld
network communications. Ultimately, this work demonstrates that advanced
security proto
cols can be successfully translated into practical, scalable, and userfriendly
management tools for securing modern IoT deployments. |
