Anti-Cloning Credential Architecture for Device Identity Provisioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloning of device identities poses significant security threats by allowing unauthorized access and transactions, and existing anti-cloning techniques are localized and do not address systemic weaknesses across different platforms and environments.
Innovation Solution
A comprehensive anti-cloning mechanism is implemented throughout the end-to-end provisioning system, including factory stations, servers, and devices, with multi-layer encryption and monitoring to prevent cloning and ensure secure credential distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If localized anti-cloning techniques are used, then cloning detection capability is improved, but system-wide coverage and comprehensive protection deteriorate
Solution Approach 1:
The patent implements a universal anti-cloning system that operates across multiple platforms and environments (factory stations, servers, devices). The system uses a standardized credential verification mechanism that can be deployed universally across different provisioning scenarios, making the anti-cloning protection adaptable and comprehensive rather than localized to specific components.
2Reliability
If multi-layer encryption and monitoring are implemented throughout the system, then security against cloning is improved, but system complexity increases
Solution Approach 1:
The patent segments the anti-cloning protection into distinct layers: credential generation at factory stations, secure transmission to servers, and verification at devices. Each layer implements specific encryption and monitoring functions independently, which reduces overall system complexity by breaking down the complex security mechanism into manageable, modular components that can be implemented and maintained separately.
3Measurement precision
If comprehensive end-to-end monitoring is deployed across all platforms, then cloning detection accuracy is improved, but processing overhead and system performance deteriorate
Solution Approach 1:
The patent implements preliminary credential binding during the device provisioning phase, where credentials are securely bound to specific devices before they enter service. This preliminary action establishes anti-cloning protection upfront, eliminating the need for continuous complex monitoring during operation. The system performs verification checks at critical transition points rather than constant monitoring, reducing processing overhead while maintaining detection accuracy.
Data Source
AI summary
A method and apparatus, and system for providing device credentials to a plurality of devices is disclosed. The system comprises a credential builder, for generating the credentials or procuring the credentials from a source external to the credential distribution system; a credential loader; a credential server, for accepting credential requests from the devices and for receiving the requested credentials from the credential loader; a first secured interface, communicatively coupling the credential loader and the credential server; a second secured interface, communicatively coupling the credential server and the device; a central credential database, communicatively coupled to the credential loader, for storing each the credentials and a provisioning history of each of the credentials; a credential server database, communicatively coupled to the credential server, for storing the credentials local to the credential server; and a cloning detection system, communicatively coupled to the central credential database and the credential server database, the cloning detection system for detecting duplicate credentials using the credentials stored in the central credential database and the credential server database.
