Ventilator Authentication Files for Secure Remote Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilator identification methods lack secure authentication, allowing impersonation and data integrity issues, especially when hardware components are defective.
Innovation Solution
A method involving an authentication file with a signature code from a signing authority, verified using a public keycode, ensures the ventilator's authenticity before data transfer, with therapeutic data processing only after successful authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identification methods from prior art are used to identify the ventilator, then the ventilator can be identified at the remote station, but secure authentication is not provided allowing impersonation and data integrity issues
Solution Approach 1:
The authentication file is created and signed by the signing authority before the ventilator connects to the remote station. This preliminary authentication setup ensures that when the ventilator connects, it already possesses verified credentials, eliminating the need for complex runtime authentication negotiations and providing secure authentication from the outset.
Solution Approach 2:
A signing authority acts as an intermediary between the ventilator manufacturer and the remote station. This trusted third party signs the authentication file, creating a chain of trust that allows the remote station to verify ventilator identity without direct complex authentication protocols between the ventilator and remote station.
2Reliability
If hardware components are defective, then identification features are lost, but this creates further problems with identification
Solution Approach 1:
The authentication file contains a digital signature that serves as a cryptographic copy of the ventilator's identity credentials. This digital copy can be verified by the remote station without relying on physical hardware components, allowing identification to persist even when hardware components become defective or are replaced.
Solution Approach 2:
The authentication file is created and stored in the ventilator's memory before hardware components may fail. This preliminary storage of authentication credentials in non-volatile memory ensures that identification information survives hardware defects and replacements, maintaining identification reliability.

AI summary
Method for authenticating at least one ventilator with at least one remote station, wherein the ventilator can connect itself via at least one interface to the remote station, at least one authentication file is stored on the ventilator, the authentication file contains at least one signature code of a signing authority, and a public keycode of the signing authority is known to the remote station, the ventilator sends the authentication file to the remote station when establishing the connection to the remote station, the remote station checks the signature code of the authentication file using the public keycode as to whether the signature code originates from the signing point and the ventilator is authenticated when the remote station recognizes the signature code as originating from the signing authority.
