Keyless Entry Signal Validation via Dynamic RF Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transportation systems lack secure and efficient methods for authenticating and authorizing vehicle operations, particularly in varying environmental security levels and proximity to other vehicles, which can lead to unauthorized access and safety risks.
Innovation Solution
A system that establishes a security level based on the vehicle's environment, determines the minimal radio frequency signal strength needed for communication, and performs commands only when this strength is achieved, using a combination of blockchain technology and radio frequency signaling to ensure secure and authorized interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If keyless entry systems allow remote commands to be performed on a transport, then ease of operation is improved, but security vulnerability increases due to unauthorized access risks
Solution Approach 1:
The system dynamically changes the RF signal strength parameter based on environmental security levels. When the transport is in a secure environment (e.g., private driveway), higher signal strengths are permitted enabling convenient remote operation. When in public or high-risk areas, the system reduces maximum permitted signal strength to prevent unauthorized remote commands, thus resolving the contradiction between ease of operation and security.
Solution Approach 2:
The keyless entry system transitions from static authorization to dynamic authorization based on real-time environmental assessment. The processor continuously evaluates security levels and adjusts command execution permissions accordingly, allowing the system to adapt its security posture and operational constraints dynamically rather than using fixed rules.
2Productivity
If the transport performs commands based on RF signals, then productivity is improved through automated operations, but security risk increases from potential unauthorized control
Solution Approach 1:
The processor acts as an intermediary between the RF signal receiver and command execution. It introduces a security evaluation layer that assesses environmental conditions and validates whether commanded operations should be permitted, preventing direct execution of potentially harmful commands while allowing legitimate automated operations to proceed.
Solution Approach 2:
The system performs preliminary security assessments before executing commands by evaluating environmental security levels and determining maximum permitted RF signal strengths in advance. This preemptive validation prevents unauthorized commands from being executed while maintaining productivity for authorized operations.
3Reliability
If the system establishes security levels based on environment, then security is improved, but device complexity increases due to additional processing requirements
Solution Approach 1:
The transport system performs self-assessment of its environmental security level using its own sensors and processors without requiring external authentication servers or complex third-party verification systems. The processor evaluates signals from key fobs, analyzes RF signal strengths, and determines security levels autonomously, reducing overall system complexity while maintaining high security.

AI summary
An example operation includes one or more of establishing a security level based on an environment of a transport, determining a minimal radio frequency signal strength needed for a device to communicate with the transport based on the security level of the transport, and performing a command, by the transport, based on the communication when the minimal radio frequency signal strength is achieved.
