Auxiliary Display Security Module Encryption Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current auxiliary display systems are vulnerable to forgery by malicious programs and lack reliable information display, leading to security concerns in electronic transactions due to their low security and user ignorance of security clues.
Innovation Solution
An auxiliary display system with a client and server architecture that uses a shared encryption key to encrypt and verify information, incorporating a security module for decryption and validation, along with an authentication center for key management and initialization, to prevent forgery and ensure reliable information display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sideshow display is used to provide security clues to users, then users can receive security information, but the display can be easily forged by malicious programs due to lack of encryption and validation
Solution Approach 1:
The patent applies preliminary anti-action by implementing encryption and digital signature verification before the malicious programs can forge the display content. The security module pre-establishes encryption keys and validation mechanisms that automatically detect and reject forged information, preventing the harmful effect before it can occur.
Solution Approach 2:
The patent introduces a security module as an intermediary between the display system and the user interface. This intermediary layer encrypts the display content and validates digital signatures, acting as a mediator that prevents malicious programs from directly forging the display while still allowing legitimate security information to be displayed to users.
2Reliability
If encryption and verification mechanisms are added to the auxiliary display system, then information security is improved, but the device complexity increases
Solution Approach 1:
The patent merges the encryption, digital signature verification, and display functions into a single integrated security module. This consolidation reduces the overall system complexity by combining multiple security functions into one unified component rather than implementing separate encryption and verification systems.
Solution Approach 2:
The security module is designed with multi-functionality, handling encryption, decryption, digital signature verification, and key management within a single component. This universal approach reduces the number of separate devices needed and simplifies the overall system architecture while maintaining high security standards.

AI summary
The present invention provides an auxiliary display system, device and method. The auxiliary display system includes a client and a server. The client includes an auxiliary display unit which further includes a security module. The server generates information to be shown in the auxiliary display unit, and uses a shared encryption key of the auxiliary display unit to encrypt the information. The security module uses the shared encryption key to verify validity of encrypted information from the server, and decrypts the encrypted information so that the decrypted information will be shown in the auxiliary display unit. The present invention can prevent from forging the auxiliary display information by malicious programs and provide users with reliable information display, and improve experience of the users.
