Mobile Device Certificate Segmentation for Broadcast Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face challenges in verifying the authenticity and integrity of communication messages transmitted by mobile devices, particularly as the number of devices increases, leading to interference and reduced communication quality.
Innovation Solution
Mobile devices, such as UAVs, partition certificates into segments and embed these segments into frames for sequential transmission, allowing receivers to authenticate the broadcast remote identification by concatenating the segments to form the certificate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of mobile devices in a region increases, then communication capacity and network utilization improve, but verification difficulty and interference increase
Solution Approach 1:
The patent segments the certificate into multiple parts that are transmitted separately. Each mobile device transmits only its corresponding certificate part, which reduces the verification burden on receivers while maintaining authentication capability. This segmentation allows the system to scale with the number of devices without proportionally increasing verification complexity.
2Productivity
If the number of mobile devices in a region increases, then communication capacity improves, but communication quality and reliability deteriorate due to interference
Solution Approach 1:
By dividing the certificate into separate parts transmitted at different times, the patent reduces simultaneous transmission interference. Each device's certificate part is transmitted independently, allowing receivers to accumulate and verify parts without experiencing the interference of multiple full certificate transmissions occurring simultaneously.
Solution Approach 2:
The patent implements preliminary actions by having mobile devices transmit their certificate parts before actual communication occurs. This preliminary transmission of authentication information allows receivers to prepare verification processes in advance, reducing the impact of interference during actual data communication.
3Measurement precision
If full certificates are transmitted for each mobile device, then authentication accuracy improves, but data transmission overhead and time increase
Solution Approach 1:
The patent segments the certificate into multiple smaller parts that can be transmitted in parallel or at different times. This segmentation maintains authentication accuracy by providing complete certificate information to receivers while reducing transmission time compared to sending full certificates simultaneously for all devices.
Solution Approach 2:
The patent performs preliminary transmission of certificate parts before actual communication needs occur. This allows receivers to receive and process authentication information in advance, reducing the time required during actual data transmission and improving overall system efficiency.
