Position Information Access Control via Two-Stage Decryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning systems face challenges in providing accurate and secure access to position information, particularly in urban areas and indoors, due to limitations in location accuracy, signal interference, and unauthorized access, which can lead to delays in emergency services and bandwidth inefficiencies.
Innovation Solution
A two-stage decryption system for position information, using air-link access certificates (ALACs) and service-level decryption keys (ASLCs), ensures that only authorized receivers and applications access encrypted positioning signals, enhancing security and allowing for tiered service levels and accurate location determination without compromising system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If position information is transmitted without access control, then all devices can access position information, but bandwidth burdens increase and unauthorized access occurs
Solution Approach 1:
The patent segments position information into multiple components (encrypted position data, decryption keys, service level indicators) and transmits them selectively based on receiver authorization. This allows the system to reduce bandwidth burden by only transmitting necessary components to authorized receivers while maintaining reliable access control through cryptographic segmentation of the information stream.
2Reliability
If position information is encrypted with multiple decryption keys, then access security improves, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-provisioning receivers with authorization data and service level information before position information transmission. The system prepares encrypted position information with embedded service level indicators in advance, allowing receivers to quickly verify authorization and decrypt only the appropriate service level without complex real-time decision-making, thus reducing operational complexity while maintaining security.
3Adaptability or versatility
If position information is transmitted to multiple applications, then service versatility improves, but bandwidth consumption increases
Solution Approach 1:
The patent applies local quality by assigning different service levels and authorization permissions to different applications and receivers based on their specific needs. The system transmits position information with embedded service level indicators that enable each receiver to decrypt and process only the portion of position data appropriate for its authorized service level, thereby providing versatile multi-application support while minimizing bandwidth consumption by avoiding redundant transmissions of full position data to all applications.
