Encrypted Data Transfer Over Intermittently Limited Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy-duty vehicles face challenges in securely transferring large data sets with intermittent volume limits on data links, particularly due to fluctuations in network quality and the need to comply with data protection regulations, especially when dealing with sensitive data like faces and number plates.
Innovation Solution
A computer system encrypts data using an asymmetric key pair, shares the private key with the recipient system, and transfers the encrypted data set during periods when the volume limit is not applied, ensuring secure and efficient data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If large data sets are stored in vehicle memory for ML model refinement and evaluation, then data availability for model improvement is improved, but data protection risk increases due to potential unauthorized access and regulatory compliance issues
Solution Approach 1:
The system performs preliminary encryption of large data sets before storing them in vehicle memory. By encrypting the data using asymmetric cryptography (generating key pairs and encrypting with the public key) before storage, the system prepares the data in advance to prevent unauthorized access while maintaining availability for ML model refinement and evaluation.
2Object-affected harmful factors
If data is transferred to external storage space to improve data protection, then data protection level is improved, but transfer reliability deteriorates due to intermittent volume limits and poor network coverage
Solution Approach 1:
The system performs preliminary encryption of data sets before transfer to external storage. By encrypting the data in advance using asymmetric cryptography, the system ensures that even if transfer interruptions occur due to intermittent volume limits or poor network coverage, the data remains protected and can be transferred securely when network conditions improve.
Solution Approach 2:
The system dynamically adapts to intermittent network conditions by waiting for appropriate transfer windows when volume limits are lifted or network coverage improves. The encryption mechanism remains static and reliable throughout, while the transfer timing dynamically responds to changing network conditions, ensuring both security and reliability.
3Productivity
If data transfer is performed during periods when volume limit applies, then transfer speed is improved, but data exposure to unauthorized access increases
Solution Approach 1:
The system performs preliminary encryption of data sets before any transfer operation. By encrypting the data in advance using asymmetric cryptography, the system ensures that data is protected regardless of when transfer occurs, including during periods when volume limits apply. This eliminates the trade-off between transfer speed and data exposure risk.

AI summary
A computer-implemented method safely transfers a large data set from a sender system to a recipient system, which are connected by a data link to which a volume limit applies intermittently. The method is performed by processing circuitry in the sender system and includes obtaining a data set; generating an asymmetric key pair comprising a private key and a public key; sharing the private key of the asymmetric key pair with the recipient system; encrypting the data set using the public key of the asymmetric key pair, for thereby obtaining an encrypted data set which is decryptable only by means of the private key; awaiting a time period in which the volume limit does not apply to the data link; and, in that time period, transferring the encrypted data set to the recipient system over the data link.
