Multi-Modal Delivery Device Authentication via Cloud Tokens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-modal delivery systems lack a common authentication framework, making them vulnerable to device-in-the-middle attacks, especially when different companies or human actors are integrated into the delivery chain, compromising security.
Innovation Solution
A multi-modal authentication system that generates and shares data packets with unique metadata for device identity, payload information, and delivery mission details, using pre-identified devices with static or dynamic tokens for authentication, and optional image-based authentication for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional device-to-device authentication is used in multi-modal delivery systems, then device identification is achieved, but the system remains vulnerable to device-in-the-middle attacks due to lack of common authentication framework
Solution Approach 1:
The patent implements a universal authentication framework where a single authentication message structure serves multiple devices and delivery modes simultaneously. The authentication message includes device identity, public key, and signature fields that work across ground-based vehicles, air-based drones, and maritime vehicles, eliminating the need for separate authentication mechanisms for each device type and resolving the vulnerability to device-in-the-middle attacks while maintaining system-wide security consistency
Solution Approach 2:
The patent introduces an intermediary authentication mechanism where each device verifies the authenticity of other devices through cryptographic signatures before establishing trust relationships. This intermediary verification process prevents direct unauthenticated connections between devices, blocking device-in-the-middle attacks by ensuring that all communication paths are validated through cryptographic proof of identity
2Adaptability or versatility
If multiple devices and vehicles coordinate in multi-modal delivery, then delivery capability is enhanced, but security vulnerabilities increase due to lack of common authentication framework
Solution Approach 1:
The authentication framework provides universal security validation across all delivery modes including ground-based vehicles, air-based drones, and maritime vehicles. The same authentication message structure and verification process applies regardless of the combination of devices involved, enabling secure coordination between multiple devices while preventing security threats through consistent cryptographic verification
Solution Approach 2:
The system implements feedback through authentication verification where each device must successfully validate the cryptographic signatures of other devices before participating in coordinated delivery operations. This feedback mechanism ensures that only authenticated devices can join the delivery network, preventing unauthorized devices from exploiting multi-modal coordination for malicious purposes

AI summary
A method for authenticating payload delivery devices. The payload delivery devices can include autonomous robotic delivery vehicles or other devices. The disclosed method causes delivery devices to authenticate each other during the delivery cycle via the cloud by determining, via a processor, payload delivery mission metadata that can include a mission identification (ID), payload information, and a mission type associated with payload delivery. The method further includes generating, based on the payload delivery mission metadata, a multi-modal authentication message that, when received by a first delivery device, configures the first delivery device to authenticate a second delivery device using a token generated onboard the delivery device or received from the cloud server, receive and authenticate delivery payload associated with the payload delivery mission, and complete a delivery operation through cloud server-coordinated or independent device authentication.
