Solution Overview

Problem

Existing electronic devices with secure circuitry face challenges in securely storing and managing sensitive data, such as biometric and payment information, due to limitations in secure data storage and authentication methods, particularly in ensuring high security against external attacks and physical vulnerabilities.

Innovation Solution

An electronic device is designed with a processor, memory, and secure circuitry connected via a physical channel, allowing data to be securely stored and authenticated using an embedded secure element (eSE) for high-security operations, including biometric data and payment information, with encryption and key management processes to enhance security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If secure circuitry is managed only by external server control commands, then security protection from external attacks is improved, but operational flexibility and mutual operation with other circuits deteriorate

Engineering Contradiction:
Improvesecurity protectionVSAvoidoperational flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent divides the control system into two segments: external server control for security-critical operations and local processor control for operational flexibility. The secure circuitry can be managed by external server control commands for high-security operations while also allowing local control for mutual operation with other circuits, resolving the contradiction between security protection and operational flexibility

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary mechanism that allows the secure circuitry to receive control commands from both external servers and local processors. This intermediary control structure enables the secure circuitry to switch between external management mode (for security) and local management mode (for operational flexibility), thus resolving the contradiction

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If data is stored in secure circuitry over physical channels, then security against external attacks is improved, but device complexity increases

Engineering Contradiction:
Improvesecurity against external attacksVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the secure circuitry with the existing device architecture through standardized physical channel connections. By integrating the secure element into the device's existing communication infrastructure rather than creating entirely separate secure pathways, the patent achieves enhanced security while minimizing the increase in device complexity

Inventive Principle:
Principle #5Merging (Combining)
