UICC Servlet Web Server for Remote Application Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Toolkit application for remote application management in smart cards is inefficient, particularly when managing tasks that require large data transfers, such as the installation of large-sized applications, due to its communication protocol limitations.
Innovation Solution
Implementing a Servlet managed by the Smart Card Web Server (SCWS) that performs remote application management functions, utilizing the http or https protocol over TCP-IP to enhance efficiency and performance, allowing for more efficient command processing and data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the existing Toolkit application communication protocol is used for remote application management, then compatibility with existing smart card standards is maintained, but efficiency and performance for large data transfers deteriorates
Solution Approach 1:
The patent introduces an HTTP-type protocol layer as an intermediary between the smart card and remote device, wrapping the existing Toolkit application commands. This mediator enables efficient web-based communication for large data transfers while preserving compatibility with the underlying smart card standards through the encapsulation of traditional command structures within the HTTP framework.
2Speed
If the Toolkit application protocol is used for managing large-sized applications, then existing smart card standards are followed, but data transfer speed and performance deteriorates
Solution Approach 1:
The patent segments the data transfer process into multiple HTTP requests and responses, allowing large-sized applications to be transmitted in manageable chunks. This segmentation enables the use of efficient web protocols for speed while maintaining reliability through the structured, standardized HTTP framework that can be reliably processed by existing infrastructure.
3Productivity
If traditional smart card communication methods are used, then security is maintained, but performance for web-based application management deteriorates
Solution Approach 1:
The patent implements a universal HTTP-based communication interface that serves multiple functions: it enables web browser access for ease of operation, maintains security through HTTPS protocols, and supports efficient data transfer for application management. This multi-functional approach allows a single standardized interface to satisfy diverse requirements simultaneously.
