Primary Processor Selection for Vehicle Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems that manage multiple on-board devices in a vehicle for encrypted communication with a server face increased resource utilization on the server side, as each device requires a unique encryption key, leading to inefficiencies as the number of devices increases.
Innovation Solution
A communication system where multiple processors determine a primary processor based on processability, network distance, or cipher strengths, with unencrypted data transferred to and encrypted by the primary processor for communication with the server, reducing the server's resource burden by using a single encryption key for all devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each on-board device performs encrypted communication with the server using a unique encryption key, then communication security is maintained for each device, but the server resources used for the encrypted communication process increase in accordance with the number of on-board devices
Solution Approach 1:
Multiple on-board devices are merged into a single encrypted communication session with the server. Instead of each device establishing separate encrypted connections with unique encryption keys, multiple devices can participate in one shared encrypted communication session, thereby reducing the number of encryption keys and server resources required while maintaining communication security.
2Reliability
If multiple on-board devices independently perform encrypted communication with the server, then each device can communicate securely, but the device complexity and configuration management become more complex
Solution Approach 1:
A single encrypted communication session is designed to serve multiple on-board devices simultaneously. The communication session has universal functionality that allows any number of authorized devices to join and communicate securely with the server through the same session, eliminating the need for separate configurations for each device and simplifying system management.

AI summary
A communication system includes a plurality of processors coupled with a network, each of the processors having a predefined encryption method for a communication with a server. Each of the processors configured to determine a primary processor of the processors based on at least one of a processability of the processor, network distance to the processor, or cipher strengths, when the processor is not determined as the primary processor, transfer unencrypted communication data through the network to the primary processor, and when the processor is determined as the primary processor, perform an encryption of unencrypted communication data received, and an encrypted communication with the server by the encryption method of the primary processor.
