Service Termination Notification Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for notifying clients of service termination over non-encrypted channels are vulnerable to denial of service attacks, as unauthorized parties can spoof termination of service (ToS) packets, compromising security.
Innovation Solution
A method and system that establish authentication data and notification data during provisioning, allowing client devices to authenticate ToS notifications through stored authentication data, even when sent over non-secure channels, ensuring the integrity of service termination notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ToS packets are sent over non-encrypted channels, then notification delivery is simplified and more widely accessible, but security is compromised allowing spoofing attacks
Solution Approach 1:
Authentication data is established and stored in the client device during the provisioning operation, before the actual service termination notification is needed. This preliminary setup enables the client to later authenticate ToS notifications independently without requiring secure channels at notification time.
Solution Approach 2:
Authentication data acts as an intermediary element that mediates between the untrusted non-encrypted channel and the client device. This intermediary enables the client to verify the authenticity of ToS packets received over insecure channels by comparing them against the pre-stored authentication data.
2Reliability
If authentication mechanisms are implemented, then security against spoofing is improved, but system complexity increases
Solution Approach 1:
The client device performs self-authentication of ToS notifications using authentication data already stored locally in its non-volatile memory. The system does not require external authentication servers or complex real-time verification mechanisms - the client independently verifies notifications by comparing received data against its stored authentication data.
Data Source
AI summary
A method for notifying a client device of termination of at least one service provided to the client device by a server system within an enterprise network is disclosed. The method includes the step of establishing authentication data and notification data, where the authentication data is related to the notification data, and sending the authentication data to the client device for storage during a provisioning operation. When the server system identifies a termination of service, it sends the notification data to the client device, which may then authenticate the received notification data using the authentication data.
