Özet

Radiation monitoring is crucial in urban environments and critical infrastructure settings. Mass public events, nuclear power plants, and hospitals require reliable monitoring of radioactive materials and potential radiation exposure. In many situations, deploying fixed radiation detection systems (RDS) is not always feasible due to their required supporting infrastructure, which makes them difficult to implement in locations with terrain constraints or high building density. Additionally, their immobility limits their effectiveness in rapidly changing environments which makes them not feasible for deployment in catastrophic disaster scenarios such as nuclear accidents. These limitations create the need for mobile detection solutions. These mobile systems often rely on wireless communication to transmit collected data and alerts, which exposes the system to security threats such as interception, spoofing, and data manipulation. In this paper, we propose a secure and reliable wireless communication infrastructure for RDS utilizing the LoRaWAN protocol for low-power secure wireless communication together with Hardware Security Modules (HSMs) to securely manage cryptographic keys and perform authentication and encryption. The proposed solution overcomes the software-based key storage limitations inherent in standard end devices while ensuring the confidentiality, authenticity, and integrity of transmitted radiation monitoring data and alerts.
