Removable Memory Module for Secure Network Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nomadic users face challenges in securely configuring their personal computers to access corporate networks remotely due to risks like viruses and uncontrolled machine connections, requiring reliable software and secure connections, which existing solutions like CD-ROMs and USB operating systems do not adequately address, especially in automating network access configurations.
Innovation Solution
A method and device that automatically configure a terminal to access a telecommunications network using a module with stored connection parameters, incorporating a smart card for robust encryption and authentication, allowing secure data storage and access through a USB or wireless link, independent of the terminal used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a personal computer is used to access corporate networks remotely, then user convenience and mobility are improved, but security risks increase due to uncontrolled software and potential viruses
Solution Approach 1:
The system separates the operating system and application software from the user's personal computer by loading them from a removable memory device. This segmentation ensures that only approved, controlled software runs on the terminal, eliminating security risks from local software while maintaining user convenience in accessing corporate networks.
Solution Approach 2:
A removable memory device acts as an intermediary between the user's personal computer and the corporate network. It provides a controlled software environment that mediates all network access, ensuring security requirements are met while allowing users to connect from personal devices.
2Reliability
If CD-ROM or USB memory devices with operating systems are used, then software control and security are improved, but network configuration capability is lost
Solution Approach 1:
The removable memory device is designed with multi-functionality, incorporating not only the operating system but also network configuration tools, drivers, and connection parameters. This universal design enables the device to both control software execution and provide network access capabilities, resolving the limitation of prior single-function approaches.
Solution Approach 2:
Network configuration parameters, drivers, and connection settings are pre-configured in the removable memory device before use. This preliminary action eliminates the need for users to manually configure network access, allowing immediate connectivity while maintaining security control.
3Adaptability or versatility
If manual configuration of network access is required, then customization flexibility is improved, but ease of use deteriorates due to complex setup procedures
Solution Approach 1:
All network configuration parameters, including connection settings, drivers, and authentication credentials, are pre-configured in the removable memory device during manufacturing or initial setup. Users simply insert the device and connect to the network without any manual configuration, achieving both flexibility (pre-set options) and ease of use (no setup required).

AI summary
A method of configuring a terminal including initializing the terminal, and which automatically triggers at least: detecting presence of a memory by a basic input/output system of the terminal, accessing the memory by the basic input/output system, starting up an operating system stored in the memory, and starting up a driver of a telecommunication network access module, the driver of the access module being stored in the memory and configured to drive the access module through a communication link between the terminal and a telecommunication device including the access module.
