Securing Smart UAV Delivery Systems Using Zero Trust Principle-Driven Blockchain Architecture

This paper presents a novel architecture that utilizes the Zero Trust Principle to facilitate blockchain-enabled Unmanned Aerial Vehicle (UAV) delivery systems, emphasizing recipient privacy, verification, and continuous authentication. By integrating blockchain's decentralization and transparency with a Zero Trust model, the architecture ensures robust security and access control. The blockchain-based architecture guarantees data integrity and resilience, while advanced cryptographic techniques, including homomorphic encryption, ensure long-term security. Ongoing security assessment and improvement are facilitated through the maturity model's integration with blockchain technology. This innovative approach effectively mitigates cyber risks, safeguards recipient data privacy, it initiative promotes the secure and efficient use of UAVs in logistics. It emphasizes the importance of maintaining strict access controls and trust boundaries. Through adaptable security evaluations, the model addresses evolving threats, ensuring a secure environment for UAV integration into the modern supply chain while prioritizing recipient privacy and security.
