Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack effective security measures for mobile-to-mobile positioning, particularly in 5G networks, which are vulnerable to unauthorized access and manipulation of positioning signals, compromising confidentiality and integrity.
Innovation Solution
Implementing cryptographic keys and certificates for securing ranging signals between wireless communication devices, ensuring confidentiality and integrity of positioning signals through encryption and cryptographic signatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cryptographic keys and certificates are implemented for securing ranging signals, then security and integrity of positioning signals is improved, but device complexity and processing overhead increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring security materials (cryptographic keys and certificates) in the devices before positioning operations begin. The first wireless communication device obtains security materials in advance, and the second device is pre-configured with corresponding security materials, allowing secure ranging signals to be transmitted without real-time security setup delays
Solution Approach 2:
The patent uses cryptographic keys and certificates as intermediary elements that mediate the security verification process between the first and second wireless communication devices. These security materials enable the devices to authenticate each other and protect ranging signals without requiring direct complex security protocols between them
2Reliability
If security materials are obtained and processed, then confidentiality and integrity of ranging signals is improved, but processing time and latency increases
Solution Approach 1:
The first wireless communication device obtains security materials (cryptographic keys or certificates) in advance before the ranging signal transmission occurs. This preliminary acquisition of security materials eliminates the need for real-time security setup during the positioning process, reducing overall latency while maintaining integrity

AI summary
A positioning session signaling method includes: obtaining, at a first wireless communication device, first security material comprising a ranging cryptographic key, or one or more cryptographic certificates, or a combination thereof; and transmitting, from the first wireless communication device to a second wireless communication device, a ranging signal that is based on at least a first portion of the first security material, or based on second security material, or a combination thereof.
