Secure Interface for Remote Access Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote access methods to computer desktops pose a security risk due to potential data theft and unauthorized access, as they allow file transfer and networking signals, which can lead to hacking and malware infections.
Innovation Solution
A secure interface system that only transfers native human I/O signals between a remote computer and a target machine, providing isolation of file systems and networks, using a signal transfer system that mimics standard human input/output devices and includes a network interface for secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional remote access methods are used to allow file transfer and networking signals, then remote access functionality is improved, but security risk increases
Solution Approach 1:
The patent introduces a secure interface device as an intermediary between the remote computer and the target machine. This device acts as a mediator that allows remote access functionality while blocking harmful file transfers and networking signals. The secure interface receives I/O signals from the remote computer, processes them through a controlled environment, and only permits safe signals to reach the target machine, thus resolving the contradiction between enabling remote access and preventing security risks.
2Reliability
If firewalls and proxy servers are deployed to protect against unauthorized access, then security is improved, but system complexity increases
Solution Approach 1:
The patent extracts the security protection function from complex software-based solutions like firewalls and proxy servers, and implements it in a dedicated hardware device - the secure interface. By taking out the security functionality and isolating it in a separate physical device that sits between the remote computer and target machine, the system achieves reliable security protection without the complexity of configuring and maintaining multiple software layers. The secure interface handles all security decisions in hardware, simplifying the overall system architecture.

AI summary
Methods and apparatus for secure access generally comprise a secure interface operating in conjunction with a remote computer and a target machine. The secure interface may provide access to the target machine by the remote computer. The secure interface may comprise a signal transfer system configured to be coupled to the target machine. The signal transfer system may transfer native human I/O signals, but does not transfer files and does not transfer networking signals. The signal transfer system may provide the only couplings to the target machine. The secure interface may also include a network interface coupled to the signal transfer system.
