UAV Anonymity Token for Privacy-Preserving Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems for unmanned aerial vehicles (UAVs) face challenges in managing UAV identities while ensuring operator privacy, particularly in scenarios requiring anonymous operations for safety and operational purposes.
Innovation Solution
The system generates an anonymity token associated with a UAV's digital certificate, allowing the UAV to operate anonymously by using this token in place of its digital certificate for authentication purposes. This token can include a cryptographically verifiable indication of its association with the digital certificate and may be configured with usability time or geographic limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a digital certificate is used for UAV authentication, then authentication integrity is improved, but operator privacy is worsened
Solution Approach 1:
The authentication system is segmented into two distinct components: digital certificates for authentication integrity and anonymity tokens for privacy protection. The anonymity token is generated as a separate entity from the digital certificate, allowing the UAV to present the token instead of the certificate in scenarios where privacy is required, thus resolving the contradiction between authentication integrity and operator privacy
Solution Approach 2:
The anonymity token acts as an intermediary between the UAV and the authentication system. It provides a cryptographic link to the digital certificate without exposing the certificate itself or any identifying information. The token includes a cryptographically verifiable indication of association with the digital certificate, enabling verification while maintaining privacy
2Loss of information
If anonymity token is introduced for privacy protection, then operator privacy is improved, but system complexity is worsened
Solution Approach 1:
The anonymity token is generated in advance by the network computing device before the UAV needs to operate anonymously. This preliminary action includes creating the token, establishing its cryptographic association with the digital certificate, and configuring any necessary limitations. By performing these actions beforehand, the system avoids the complexity of real-time token generation and verification during UAV operations
Solution Approach 2:
The anonymity token serves as a cryptographic copy or representation of the digital certificate's authentication capability without containing the certificate itself. It replicates the essential authentication function while excluding identifying information, thus simplifying the privacy protection mechanism compared to more complex anonymization approaches
3Reliability
If anonymity token with limitations is used, then operational security is improved, but flexibility is worsened
Solution Approach 1:
The anonymity token system is designed to be dynamic and configurable. Limitations such as usability time limitations and geographic limitations can be applied selectively based on operational requirements. The network computing device can configure different limitation levels for different tokens, allowing the system to adapt between highly secure restricted operations and more flexible operations as needed

AI summary
In embodiments of systems and methods for managing an unmanned aerial vehicle (UAV) identity, a processor of a network computing device may generate an anonymity token that is associated with a digital certificate of a UAV, provide the anonymity token to the UAV for use in operations, receive a request to authenticate the UAV, wherein the request includes the anonymity token, determine whether the anonymity token included in the request is associated with the digital certificate, and send an indication that the UAV is authenticated responsive to the request in response to determining that the anonymity token included in the request is associated with the digital certificate.
