Universal Authenticator Reduces Bandwidth in Data Subsets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of subsets in a data source increases, the bandwidth usage and the time required to update devices in a network also increase, due to the need to provide authentication information for each subset, which can slow down the process and consume more network resources.
Innovation Solution
The use of a changing secret value to generate a non-secret value, which is then used to authenticate data, minimizing the bandwidth required by using a universal non-secret value that can be processed by various recipient devices, thereby reducing the need for multiple data blocks for each type of recipient device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication information is provided for each subset of recipient devices, then authentication reliability is improved, but bandwidth usage increases
Solution Approach 1:
The patent combines authentication information for multiple subsets into a single aggregated authentication message. Instead of transmitting separate authentication data for each subset, the system merges them into one consolidated message that can be processed by all recipient devices, thereby reducing bandwidth usage while maintaining authentication reliability.
Solution Approach 2:
The patent creates a universal authentication message that serves multiple subsets simultaneously. This single authentication structure is designed to be universally applicable across different subsets of recipient devices, eliminating the need for separate authentication transmissions for each subset and thus reducing overall bandwidth consumption.
2Reliability
If authentication information is provided for each subset of recipient devices, then authentication completeness is improved, but update time increases
Solution Approach 1:
The patent merges authentication operations into a single aggregated process. By combining multiple subset authentications into one unified message and processing step, the system reduces the total time required for updates while ensuring all subsets receive appropriate authentication information.
Solution Approach 2:
The patent performs preliminary organization of authentication information into aggregated structures before transmission. By pre-processing and consolidating authentication data into universal messages, the system eliminates redundant transmission and processing steps, thereby reducing overall update time while maintaining completeness.
3Measurement precision
If separate authentication messages are sent to each recipient device, then authentication precision is improved, but device complexity increases
Solution Approach 1:
The patent designs a universal authentication message structure that maintains precise authentication capabilities across different subsets without requiring complex device-specific implementations. This universal structure simplifies the system architecture while preserving authentication precision through standardized processing rules.
Solution Approach 2:
The patent employs homogeneous authentication message formats and processing procedures that work uniformly across all subsets. This homogeneity reduces system complexity by eliminating the need for diverse handling mechanisms, while authentication precision is maintained through consistent application of the same rigorous validation rules to all messages.
