Solution Overview
Problem
The sharing economy faces challenges in managing secure and reliable sharing services due to unauthorized access and resource-intensive logistics management, with issues such as unlawful package switching and theft, and existing systems lack effective identity verification and resource determination.
Innovation Solution
A sharing service encryption system utilizing physical unclonable functions (PUFs) for identity verification and resource determination, combined with asymmetric encryption, to securely manage user, logistics package, and mobile vehicle access to sharing resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical unclonable functions and asymmetric encryption are used for identity verification, then security level is improved, but system complexity increases
Solution Approach 1:
The patent introduces a verification unit as an intermediary component that handles the complex cryptographic operations. This verification unit mediates between the identity information and the sharing resource determination, encapsulating the complexity of PUF and asymmetric encryption operations while presenting a simplified interface for security verification.
Solution Approach 2:
The system is segmented into distinct functional units: a verification unit that handles cryptographic verification, a sharing resource determination unit that decides access rights, and a database that stores verification information. This segmentation allows each component to manage specific complexity while maintaining overall system security.
2Reliability
If multiple encryption steps are applied to public keys, then decryption difficulty increases, but key management complexity increases
Solution Approach 1:
The patent combines multiple encryption steps into a unified verification process. The verification unit integrates PUF-based key generation, asymmetric encryption, and public key encryption into a single coherent mechanism, where the complexity is merged into one verification operation rather than separate management steps.
Solution Approach 2:
The system performs self-service encryption where the verification unit automatically generates and manages encryption keys based on PUF characteristics. The public key encryption and verification operations are performed autonomously without requiring manual key management or complex cryptographic operations from the user side.
3Reliability
If identity information is encrypted and verified before resource access, then unauthorized access is prevented, but processing time increases
Solution Approach 1:
The system performs preliminary verification actions by pre-storing verification information in the database before actual resource access is needed. When access is required, the verification unit quickly retrieves and validates pre-processed information, reducing the time needed for real-time authentication while maintaining strong security.
Solution Approach 2:
The patent uses cryptographic copying of verification information. Instead of storing sensitive data in plaintext, the system creates and stores encrypted copies of verification information. This allows rapid verification through cryptographic operations rather than data comparison, reducing processing time while maintaining security.
