Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If end-to-end encryption is maintained between data source devices and data processor devices, then data security is improved, but encryption key updates require frequent network communication which increases bandwidth consumption
Solution Approach 1:
An information gateway is introduced as an intermediary between data source devices and data processor devices. The gateway maintains encryption key information and performs decryption/ re-encryption operations, allowing key updates to be propagated through the gateway rather than requiring direct communication with all data source devices. This mediator approach maintains security while reducing overall network bandwidth consumption for key distribution.
Solution Approach 2:
The encryption key management function is extracted from the end-to-end communication path and centralized at the information gateway. By separating key management from data transmission, the system allows key updates to be managed centrally without requiring frequent full-data re-transmission or direct updates to all data source devices, thus reducing bandwidth consumption while maintaining security.
2Reliability
If encryption keys are updated frequently across all data source devices, then information security is improved, but the complexity of managing and communicating updates to all devices increases
Solution Approach 1:
The patent merges the encryption key management functionality into a centralized information gateway that serves multiple data source devices. Instead of each device independently managing and updating encryption keys, the gateway consolidates this function, storing key information and handling updates for multiple devices through a single point of control, thereby reducing overall system complexity.
Solution Approach 2:
The information gateway performs multiple functions including routing data requests, managing encryption keys for multiple data source devices, and coordinating with data processor devices. This multi-functional approach eliminates the need for separate key management systems at each device, simplifying the overall architecture while maintaining security.
3Adaptability or versatility
If sensitive information is transmitted frequently over the network for updates, then data processor devices can maintain current encryption information, but the risk of unauthorized access and data leakage increases
Solution Approach 1:
The information gateway acts as a secure intermediary that handles sensitive encryption key information. Instead of transmitting sensitive data directly between data source devices and data processor devices, all key-related communications are routed through the gateway, which can implement additional security measures and reduce the attack surface for potential unauthorized access.
Solution Approach 2:
The patent extracts sensitive encryption key information from general data transmission channels and handles it through specialized gateway mechanisms. This separation allows the system to maintain current encryption information while using dedicated secure pathways for key management, reducing the risk associated with transmitting sensitive information over general network channels.
Data Source
AI summary
A device is configured to receive a data request that includes an encrypted data element. The device is further configured to identify a data source device associated with the data request, to identify a first encryption key associated with the data source device, and to decrypt the encrypted data element using the first encryption key. The device is further configured to identify a first data processor device associated with receiving the data request, to identify a second encryption key associated with the first data processor device, wherein the second encryption key is different from the first encryption key, and to re-encrypt the decrypted data element. The device is further configured to identify routing instructions associated with the first data processor device and to send the re-encrypted data element to the first data processor device in accordance with the routing instructions.
