Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for emergency vehicles to pass through traffic lights quickly are risky and lack dedicated authentication protocols, leading to potential secondary accidents and inadequate security.
Innovation Solution
An authentication method using elliptic curve cryptography and physically unclonable functions (PUFs) for secure authentication of emergency vehicles to ensure secure communication between vehicles, roadside units, and traffic control units, incorporating biometric verification and secure storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If emergency vehicles directly run red lights to pass through quickly, then the passage speed is improved, but the safety and risk level deteriorate
Solution Approach 1:
The system performs preliminary authentication and traffic light control adjustments before the emergency vehicle arrives. The authentication process pre-establishes communication channels and authorization, while the traffic light control system pre-adjusts signal phases to green in advance of the vehicle's arrival, eliminating the need for the vehicle to run red lights while maintaining high speed passage.
2Reliability
If traditional authentication protocols are used for emergency vehicles, then security is improved, but the authentication time and passage efficiency deteriorate
Solution Approach 1:
Emergency vehicles undergo authentication and receive authorization tokens in advance before reaching traffic light intersections. The authentication process is completed preliminarily, and the vehicle carries pre-validated credentials that enable rapid verification at intersection points without requiring time-consuming authentication procedures during actual passage.
Solution Approach 2:
The authentication system implements a fast-pass mechanism where pre-authenticated emergency vehicles can skip detailed verification steps at traffic light intersections. The system trusts pre-validated vehicles and allows them to rapidly pass through authentication checkpoints without undergoing complete re-authentication, significantly reducing authentication time while maintaining security through the initial rigorous authentication process.

AI summary
The proposed invention discloses an authentication method for emergency vehicles to quickly pass through traffic lights, which relates to the field of information security technology. The method designs a traffic light service request message propagation and handover authentication structure by considering that traffic lights are located in different roadside unit domains, enabling emergency vehicles to quickly pass through multiple traffic lights until they reach the intended destination. By introducing elliptic curve encryption operations on critical parameters during the authentication process, the security of the entire authentication process is enhanced, effectively resisting various known attacks. The adoption of elliptic curve Diffie-Hellman secret exchange values for authentication ensures the legitimacy of identities. Vehicles employ a dynamic anonymity strategy to protect privacy, avoiding the transmission of identity-related information over public channels and achieving privacy protection.
