Third-Party UE Control Using Privacy-Preserving Authorization Tokens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly in V2X and D2D technologies, lack mechanisms for secure and privacy-preserving third-party control of user equipment (UE) without revealing the true identity of the UE, which is essential for scenarios like controlling malfunctioning autonomous vehicles.
Innovation Solution
A mechanism is introduced where UEs are provisioned with certificates and pseudo IDs by an authority, enabling authorized third parties to request and verify control through encrypted and signed authorization IDs, ensuring privacy by using time and location-based encryption and one-way-hash verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If third-party control of UE is implemented without privacy protection, then control functionality is improved, but user privacy and security deteriorate
Solution Approach 1:
The patent introduces an authority server as an intermediary that issues signed authorization tokens. The token contains encrypted UE identifiers and authorization information, allowing the third party to control the UE without directly accessing or exposing the UE's true identity. The authority server mediates between the UE and third party, enabling control functionality while protecting privacy through cryptographic mechanisms.
Solution Approach 2:
The patent transforms the UE's permanent identifier into an encrypted form within the authorization token. By changing the parameter representation from plaintext ID to encrypted token format, the system enables third-party control while preventing identity exposure. The encrypted identifier can be decrypted only by the authorized third party with proper credentials, not by eavesdroppers or unauthorized entities.
2Reliability
If encrypted authorization mechanisms are implemented, then security and privacy are improved, but system complexity increases
Solution Approach 1:
The authority server performs cryptographic operations in advance to generate and sign the authorization token before the actual control operation. The token is pre-computed with all necessary authorization information and encrypted identifiers, so that during the actual control process, the third party only needs to present and verify the pre-generated token, reducing real-time computational complexity.
Solution Approach 2:
The patent creates a cryptographic copy (token) of the authorization information that contains encrypted references to the UE's identity and control permissions. Instead of directly handling complex cryptographic operations during control, the system uses this pre-computed cryptographic copy that encapsulates all necessary security information, simplifying the control process while maintaining security.

AI summary
A configuration for allowing a wireless device to request control of another wireless device. The apparatus receives a message from a first user equipment (UE), the message comprising a first identifier (ID). The apparatus sends a first request to an authority requesting authorization to control the first UE. The apparatus receives information from the authority for controlling the first UE. The apparatus transmits a second request for connection with the first UE to control the first UE, the second request comprising the information received from the authority.
