Secure Shell Device with Temporary Data Download
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices often lack sufficient security features, making them vulnerable to misuse by unintended users, which can compromise both user data and service provider security.
Innovation Solution
Deployment of secure shell devices with minimal software and hardware resources, where a server downloads configuration information and user data temporarily to enable communication, using security features like passwords and biometric data, and then deletes the data after use to maintain minimal resource state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If configuration information and user data are stored on the mobile device, then communication functionality is enabled, but security risk increases due to potential misuse by unintended users
Solution Approach 1:
The server performs preliminary actions by validating user credentials and preparing configuration information before transferring it to the shell device. This ensures that only authorized users receive communication capabilities, resolving the contradiction by pre-establishing security checks before functionality is enabled.
Solution Approach 2:
The server acts as an intermediary between the authentication system and the shell device. It mediates the transfer of configuration information and user data, controlling what reaches the device based on validation results. This intermediary role enables communication functionality only when security requirements are met.
2Adaptability or versatility
If configuration information and user data are downloaded to the shell device, then communication is enabled, but device resource consumption increases
Solution Approach 1:
The shell device dynamically adjusts its resource state by loading configuration information and user data only when communication is required, then deleting them afterward. This dynamic approach enables communication capability on demand while minimizing data residency, resolving the contradiction between adaptability and quantity of substance.
Solution Approach 2:
The system implements a discard-and-recover pattern where configuration information and user data are downloaded, used for communication, then deleted from the device. The server retains these data and can re-download them when needed again. This approach enables communication capability while minimizing persistent data storage on the device.
3Reliability
If the shell device maintains minimal software and hardware resources, then security is improved, but communication functionality is limited
Solution Approach 1:
The server performs preliminary validation of user credentials before transferring configuration information to the minimal shell device. This pre-authentication approach enables the device to maintain minimal resources while still providing secure communication functionality when needed, resolving the contradiction between security and adaptability.
Solution Approach 2:
The server acts as an intermediary that provides communication functionality to the minimal shell device without requiring the device itself to have extensive resources. The server handles complex authentication and data management, while the device maintains a minimal secure footprint, resolving the contradiction between security and communication capability.
Data Source
AI summary
A shell device with minimal software and/or hardware resources can download from a server configuration information and/or user data in order to allow the shell device to communicate with other computing devices (whether cell phones, personal digital assistants, laptops, and the like). Various security features can also be used herein, including a shell device password and a server network access password. In another aspect, any time code and/or data is downloaded from the server to the shell device, such code and/or data resides on the shell device during the time of a communication between the server and the shell device; thereafter, it can be deleted, thereby returning the shell device to its minimalistic resource state. When the shell device contacts the server again and attempts to establish another communication, such code and/or data can be downloaded anew, and after the communication it can be deleted again.
