Authentication Counter Resynchronization Without User Reset Prompts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card-based transaction systems face desynchronization issues with authentication counters, leading to unauthorized access and fraudulent activity due to unsynchronized counter values, and prompting users for reset is vulnerable to security threats.
Innovation Solution
A counter resynchronization system involving servers with processors that determine reset events, generate resync values, and transmit them to devices based on prioritization factors, automatically replacing counter values without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If user prompts are used for counter reset, then user awareness of counter status is improved, but security is worsened due to advance notice to malicious attackers
Solution Approach 1:
The patent extracts the counter reset notification function from the user interface and relocates it to the server-side system. The server automatically detects counter desynchronization and initiates reset without user prompts, eliminating the security vulnerability of advance notification while maintaining system awareness of counter status through backend monitoring mechanisms.
2Reliability
If manual counter reset is implemented, then counter resynchronization capability is improved, but device complexity is worsened due to user intervention requirements
Solution Approach 1:
The system implements self-service counter reset functionality where the server automatically detects counter desynchronization between the card and server, generates reset commands, and executes the reset without requiring user intervention. The server monitors counter values and autonomously manages resynchronization, eliminating manual user actions while maintaining reliable counter synchronization.
3Reliability
If automated counter reset is implemented, then security is improved by eliminating user prompts, but loss of time is worsened due to validation and transmission processes
Solution Approach 1:
The system performs preliminary counter validation and resynchronization preparation during the transaction authorization process before the actual counter reset is executed. The server pre-validates counter values, prepares reset commands, and integrates the reset operation into existing transaction flows, minimizing additional time requirements while maintaining security through automated processes.
