Abstract

In the face of modern hybrid threats and infrastructure vulnerabilities, the timely and secure dissemination of air raid alerts is vital for civilian safety. Traditional centralized alert systems are susceptible to disruption, making decentralized wireless alternatives increasingly relevant. This paper presents a secure key provisioning framework for a decentralized air raid alert system built on LoRa-based mesh networking. Each node is equipped with a cryptographic identity stored in a hardware secure element (ATECC608A), enabling message authentication, signature verification, and node revocation without centralized control. The proposed system ensures that only trusted nodes can initiate or relay alert signals, effectively preventing spoofing, replay attacks, and unauthorized activations. A series of real-world tests and simulations demonstrates that the framework introduces minimal latency while significantly enhancing system resilience and trustworthiness. The results confirm the feasibility of a scalable, tamper-resistant alert network capable of operating under degraded or hostile conditions.
