Asynchronous Data Transmission via Pre-stored Electronic Keys
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing data transmission processes, particularly for mobile users, are inefficient due to the separation of authentication and data transfer phases, leading to inconvenient user interactions and suboptimal network capacity utilization, as authentication often takes longer than necessary and may occur over less powerful networks.
Innovation Solution
The process involves generating authentication data and an electronic key, which are stored together, allowing for asynchronous transmission of encrypted data, enabling authentication and data transfer to occur at different times, with encryption and decryption handled by a central module and communications terminal, respectively, optimizing network usage and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication and data transfer are performed in separate phases with user interaction, then security is ensured, but transmission time increases and network capacity utilization decreases
Solution Approach 1:
The system performs preliminary actions by storing authentication data and electronic keys in advance on the server side. When data needs to be transmitted, the pre-stored authentication credentials enable automatic authentication without requiring user interaction at the moment of data transfer, thus reducing transmission time while maintaining security.
Solution Approach 2:
The terminal device is configured with the ability to perform automatic authentication using pre-stored credentials. The system enables self-service by allowing the terminal to automatically authenticate and receive encrypted data without requiring manual user input, thereby reducing transmission time while maintaining security through pre-configured authentication mechanisms.
2Adaptability or versatility
If authentication is performed over less powerful networks, then mobility is maintained, but transmission speed decreases
Solution Approach 1:
The system segments the data transmission process into two independent parts: authentication (which can occur over any network including mobile networks) and data transfer (which occurs over high-capacity networks). The authentication data and electronic keys are transmitted separately from the actual data content, allowing authentication to happen over mobile networks while the bulk data transfer occurs over faster networks when available.
Solution Approach 2:
The server acts as an intermediary that receives authentication requests over mobile networks, verifies credentials using pre-stored authentication data, and then initiates data transfer over high-capacity networks. This intermediary role allows the system to maintain mobility while ensuring fast data transmission by decoupling the authentication phase from the data transfer phase.
3Reliability
If VPN tunnel is set up even when no new messages are available, then secure connection is maintained, but network bandwidth is wasted
Solution Approach 1:
Instead of maintaining a continuous VPN tunnel, the system implements periodic action by establishing secure connections only when needed - specifically when new data is available for transmission or when authentication is required. The pre-stored authentication data enables quick re-establishment of secure connections on demand, eliminating the need for continuous tunnel maintenance and reducing unnecessary network bandwidth consumption.
Data Source
AI summary
In a method and a system for data transmission, authentication data and an electronic key may be generated, with the electronic key being stored as assigned to the authentication data. Data may be encrypted, such as by a central communications device, into encrypted data, using at least part of the electronic key. Based on reception of the authentication data from a communications terminal, at least a portion of the electronic key and the encrypted data may be transmitted from the central communications device to the communications terminal.
