Encrypted Action Information for Secure Vehicle Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle identification techniques based on vehicle actions are vulnerable to interception, leading to unreliable and unsafe identification of target vehicles, particularly in automated valet parking systems.
Innovation Solution
The proposed method generates and transmits encrypted information for a second action derived from a first action, using a first key, and the target vehicle restores and performs the original first action, ensuring that only the intended vehicle is identified as the target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If vehicle identification is performed based on transmitted action information, then identification speed is improved, but reliability deteriorates due to interception vulnerability
Solution Approach 1:
The patent introduces encrypted action information as an intermediary between the management system and target vehicle. The encryption acts as a mediator that protects the identification process from interception, allowing fast identification while maintaining reliability through cryptographic protection.
Solution Approach 2:
The patent transforms the action information parameter by applying encryption to it. This parameter change converts plain action information into encrypted form, which maintains the identification functionality while adding security against interception, thus resolving the contradiction between speed and reliability.
2Reliability
If encrypted action information is transmitted and verified, then identification reliability is improved, but system complexity increases
Solution Approach 1:
The target vehicle performs self-verification by decrypting the encrypted action information and executing the specified action. The management system verifies identification by checking if the executed action matches the decrypted information. This self-service approach improves reliability without requiring complex external verification infrastructure.
Solution Approach 2:
The patent applies encryption to action information before transmission as a preliminary action. This pre-processing step simplifies the overall system by handling security concerns upfront, allowing the core identification system to remain relatively simple while gaining enhanced reliability.
3Reliability
If multiple actions are transmitted for verification, then identification reliability is improved, but loss of time increases
Solution Approach 1:
The patent combines multiple verification elements into a single encrypted action information package. Instead of transmitting and verifying multiple separate actions, the system merges the verification requirements into one encrypted message that contains all necessary verification data, thus improving reliability without proportionally increasing time loss.

AI summary
A vehicle identification method for identifying a target vehicle includes the following first to sixth steps. The first step is, in a management system, generating information indicating a second action from information indicating a first action using a first key. The second step is transmitting the information indicating the second action from the management system to the target vehicle. The third step is, in the target vehicle, restoring the information indicating the first action from the information indicating the second action using a second key. The fourth step is causing the target vehicle to perform the first action. The fifth step is, in the management system, detecting an action performed by a vehicle. The sixth step is, in the management system, identifying the vehicle performing the first action as the target vehicle and not identifying the vehicle performing the second action as the target vehicle.
