The Role of Robotic Delivery Systems
The role of package delivery is pivotal across numerous industries, yet it often involves high costs and inefficiencies when relying solely on human resources. The last-mile transport problem significantly contributes to these expenses, leading to the exploration of robot-based delivery systems as a potential solution to enhance delivery efficiency.
Growing Demand and Challenges
The demand for delivery services has surged, particularly due to the growth of online shopping and the COVID-19 pandemic’s push for contactless delivery options. The relevance of robotic delivery systems has become increasingly pronounced. However, the implementation of these systems is not without challenges. They face security and privacy concerns, including impersonation, replay attacks, man-in-the-middle attacks (MITM), unlinkability, and identity theft.
Proposed Solutions and System Architecture
To address these vulnerabilities, a privacy-preserving multi-factor authentication scheme has been proposed specifically for robotic delivery systems. This protocol integrates cryptographic security with deep learning-based verification, aiming to ensure secure and efficient data exchange among the robot, server, and client.
The proposed authentication scheme includes a comprehensive security analysis against various attack models and allows user registration even under insecure channels. It features a dual authentication phase comprising both cryptographic and biometric factors, requiring users to input a subkey and undergo face and voice verification. The system architecture consists of a server, client, and robot, with secure communication protocols established between them.
Further enhancing the resilience of these systems is the introduction of a transformer-based audio-visual fusion defender designed to mitigate adversarial samples that could threaten AI-assisted robotic delivery systems. This defender was evaluated using a formal analysis with symbolic proof tools like ProVerif and Scyther.
A real-world implementation of the robotic system was tested using a Turtlebot3 integrated with a Raspberry Pi 3, programmed in Python and PyTorch. The experimental setup assessed the performance of the proposed system against various adversarial attack methods. Results indicated significant improvements in the robustness of face and voice verification systems.
Conclusion and Future Implications
In addition to addressing security, the system is designed to enhance operational efficiency and reduce carbon emissions compared to traditional delivery methods. The flexibility of delivery robots allows them to be utilized in various applications, including food services, retail, healthcare, and personal use. They are capable of operating in both structured environments like warehouses and unstructured public terrains.
The conclusion of the research underscores the imperative of combining multi-factor authentication with secure cryptographic protocols within robotic delivery systems. By doing so, the proposed scheme aims to provide mutual authentication, enhanced user privacy, strong anonymity, perfect forward secrecy, and resilience against adversarial attacks. This ensures that sensitive user data, particularly biometric information, is not stored in plain text. This holistic approach is vital for the future of secure and efficient robotic delivery systems.
