Integrated SE CPU Chip Mobile Payment Hardware Area Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile payment solutions require a separate Secure Element (SE) chip outside the primary system, leading to increased area occupation and costs on the mobile terminal's main board due to the SE and central chip being separate entities.
Innovation Solution
Integration of the SE and CPU into a single semiconductor chip, with a memory storage module for mobile payment software, allowing the processor to execute and manage payment information exchange, reducing hardware costs and space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the SE and CPU are integrated into a single semiconductor chip, then the area and cost of mobile payment hardware are reduced, but the security and reliability of payment operations may be compromised
Solution Approach 1:
The patent integrates the SE and CPU into a single semiconductor chip, merging previously separate security and processing functions into one unified component. This reduces the area occupation on the main board while maintaining functional separation through software-based isolation mechanisms that preserve security requirements.
2Ease of manufacture
If the SE and CPU are integrated into a single semiconductor chip, then the manufacturing cost is reduced, but the complexity of ensuring secure execution environments increases
Solution Approach 1:
The integration of SE and CPU into one chip simplifies manufacturing by reducing component count and assembly steps, directly lowering production costs. The secure execution environment complexity is managed through software-based isolation and virtualization techniques that emulate separate hardware boundaries within the unified chip architecture.
3Reliability
If the SE operates independently outside the primary system, then the security isolation is enhanced, but the area occupation and system complexity increase
Solution Approach 1:
The patent merges the independently operating SE with the primary system CPU into a single integrated chip, eliminating the need for separate physical placement on the main board. Security isolation is maintained through virtualized execution environments and software-based boundary enforcement within the integrated architecture, reducing area occupation while preserving security properties.
