Event-Based Key Provisioning for Secure Transport Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transportation systems lack efficient and dynamic methods to provide event-based functionalities to vehicles, such as enhanced safety features, based on real-time environmental conditions, without requiring permanent key storage which could be compromised.
Innovation Solution
A system where a transport receives temporary keys and functionalities from a server, verified through a Trusted Execution Environment, to activate specific features like enhanced traction control or anti-fog lights only when needed, using blockchain for secure and decentralized authorization and data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent keys are stored in the transport for activating functionalities, then the transport can reliably perform required functions, but the security risk increases due to potential key compromise
Solution Approach 1:
The patent implements event-based keys that are temporary and automatically expire after a single use or after a specific time period. These keys are generated on-demand by the server and stored in the transport only for the duration needed to activate a functionality. After the event occurs or the time expires, the key becomes invalid and is effectively discarded, eliminating the security risk associated with permanent key storage while maintaining reliable functional activation during the valid period
Solution Approach 2:
The system performs preliminary key generation and provisioning before the actual event occurs. The server generates the key and associated functionality data in advance, transmits it to the transport, and stores it in secure memory. The transport then has the key ready for immediate activation when the event is detected, ensuring reliable and timely functionality activation without requiring long-term key storage
2Adaptability or versatility
If the transport activates functionalities based on real-time environmental conditions, then the adaptability improves, but the system complexity increases due to event detection and key verification mechanisms
Solution Approach 1:
The patent introduces a server as an intermediary between the transport and the functionality activation process. The server receives event detection data from the transport, determines whether the event warrants functionality activation, generates the appropriate key, and transmits it back to the transport. This intermediary approach allows the transport to maintain relatively simple event detection capabilities while the server handles the complex key management and activation logic, reducing the overall system complexity at the transport level
Solution Approach 2:
The system segments the functionality activation process into distinct modular components: event detection by sensors, event data transmission to the server, key generation and verification by the server, and functionality activation by the transport. Each component operates independently with well-defined interfaces, making the overall system more manageable and easier to implement despite the increased adaptability requirements
Data Source
AI summary
An example operation includes one or more of receiving, by a transport, a key and a functionality associated with an upcoming event from a server, and performing, by the transport, the functionality when the key is verified and the event begins to occur.
