Asymmetric Cryptographic Authentication for Automated Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated delivery systems face challenges in securely and efficiently authenticating legitimate recipients for product delivery, especially when dealing with unknown or automated receiving stations, as existing methods are not quick, simple, or secure enough.
Innovation Solution
A method utilizing asymmetrical encryption with public and private cryptographic keys allows recipients to authenticate themselves by decrypting encrypted messages, enabling secure and rapid verification of authorization for product receipt, applicable to both human and automated platforms, and allowing for wireless communication without requiring internet access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional authentication methods (identification papers) are used for automated delivery, then security is maintained, but the process becomes complex and time-consuming
Solution Approach 1:
The patent replaces traditional mechanical authentication methods (physical identification papers) with a cryptographic electronic system. The deliverer's device generates and transmits encrypted messages to the recipient's device, which decrypts and verifies them automatically. This substitution of mechanical processes with electronic/cryptographic mechanisms enables rapid authentication without manual intervention, directly resolving the contradiction between authentication speed and process complexity.
2Extent of automation
If automated delivery systems are implemented, then personnel requirements are reduced, but secure authentication of unknown recipients becomes difficult
Solution Approach 1:
The patent implements preliminary authentication actions before the actual delivery occurs. The deliverer's device sends encrypted authentication messages to the recipient's device in advance, allowing the recipient to verify their identity and authorization status before the product is handed over. This preliminary cryptographic verification ensures reliable authentication of unknown recipients in automated delivery systems, maintaining security while enabling high levels of automation.
3Reliability
If encrypted message authentication is implemented, then authentication security is improved, but the requirement for cryptographic keys increases system complexity
Solution Approach 1:
The patent implements self-service authentication where the recipient's device automatically handles cryptographic operations without requiring manual intervention. The system automatically generates, stores, and uses cryptographic keys for encrypting and decrypting authentication messages. This self-service approach to cryptographic key management maintains high authentication security while minimizing the operational complexity for users, as the system manages the cryptographic infrastructure autonomously.

AI summary
A method of authentication for delivery of a product to a recipient. The method includes: a customer generating a public and a private cryptographic key in accordance with an asymmetrical encryption; the customer providing the public cryptographic key for the deliverer; the deliverer generating a message encrypted using the public cryptographic key; transmitting the encrypted message to the recipient for authentication; generating a plain text of the encrypted message in that the recipient decrypts the encrypted message using the private key; transmitting the plain text to the deliverer; and the deliverer authenticating the recipient if the transmitted plain text matches the message.
