Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic banking networks are vulnerable to computer attacks, which can lead to significant economic disruptions and negative impacts on users and banking organizations, necessitating a method to enhance resilience during such events.
Innovation Solution
A method for activating an emergency transaction mode that includes receiving and verifying an activation command with encrypted data, allowing the system to transition to an emergency mode unaffected by attacks or failures, enabling continued operations with specific transaction rules and thresholds, and deactivating when conditions are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If normal transaction mode is used, then standard banking operations can be performed, but the system is vulnerable to computer attacks and network failures
Solution Approach 1:
The transaction system is divided into two independent operational modes: normal mode and emergency mode. Each mode has its own transaction processing logic and rules. This segmentation allows the system to switch to emergency mode when attacks are detected, isolating the vulnerable normal mode from harmful factors while maintaining operational capability through the separate emergency mode pathway.
Solution Approach 2:
The system pre-configures emergency mode procedures and transaction rules before attacks occur. Activation commands with encrypted data and authentication codes are prepared in advance, allowing immediate transition to emergency mode without delay. This preliminary preparation ensures that when attacks are detected, the system can rapidly switch to the pre-established emergency procedures, minimizing disruption and maintaining reliability.
2Reliability
If emergency mode is activated, then resilience against attacks is improved, but transaction processing complexity increases
Solution Approach 1:
The emergency mode transaction logic is extracted as a separate, self-contained procedure with its own rules and validation mechanisms. By isolating emergency mode operations from normal transaction processing, the system manages complexity through clear separation of concerns. The emergency mode includes specific rules for transaction amounts, counters, and authentication that are distinct from normal mode, allowing each to be optimized independently while maintaining overall system resilience.
3Reliability
If activation command verification is performed, then security is improved, but processing time increases
Solution Approach 1:
Authentication codes and encrypted data for activation commands are verified using pre-configured security parameters and algorithms. The verification process utilizes pre-established cryptographic keys and validation rules, allowing rapid authentication without extensive real-time computation. This preliminary configuration of security parameters enables fast verification that maintains both security and processing efficiency during emergency mode activation.

AI summary
A method and device for managing an emergency procedure of an emergency transaction mode that can be activated in the event of a computer attack on or a failure of a transaction network. The method may be carried out by an electronic device suitable for performing a transaction in a normal mode or in the emergency mode. The method performs operations that may include receiving an activation command for activating the emergency mode procedure, where the command includes an identifier of the procedure and first encrypted data; verifying the activation command, which includes verifying the first encrypted data; and if verification of the command is successful, activating the emergency procedure.
