Secure Element Router for Cross-Protocol Application Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure elements face challenges in efficiently communicating with other electronic devices due to protocol incompatibilities and the need for improved data integrity and confidentiality, particularly in the context of cryptographic mechanisms.
Innovation Solution
A secure element is equipped with a router and software layer that manages multiple communication protocols, including the VNP protocol, and converts messages between different protocols to ensure compatibility and efficient data routing, using a virtual host software to translate between incompatible protocols like HCI, SWP, CLT, and ISO7816.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a secure element uses a single communication protocol, then the device complexity is reduced, but the adaptability to different electronic devices deteriorates
Solution Approach 1:
The patent introduces a router with a software layer that acts as an intermediary between multiple communication protocols. The router receives messages in different protocols (HCI, SWP, CLT, ISO7816, VNP) and translates them into a unified internal format, enabling the secure element to communicate with various external devices without requiring multiple protocol stacks in each application.
2Adaptability or versatility
If multiple communication protocols are supported, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The router is designed as a universal component that handles multiple communication protocols (HCI, SWP, CLT, ISO7816, VNP) through a single software layer. This multi-functional router consolidates protocol translation capabilities, allowing the secure element to support diverse communication standards without requiring separate processing paths for each protocol.
3Ease of operation
If protocol translation is implemented, then the ease of operation improves, but the loss of time in message processing increases
Solution Approach 1:
The router is pre-configured with translation rules and mapping tables for multiple protocols. When a message arrives, the router quickly identifies the protocol type and applies pre-computed translation mappings, reducing the time required for protocol conversion compared to dynamic protocol analysis and translation.
