Secure Telegram Generation with Dynamic Test Data Formatting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure telegram generation systems lack flexibility in formatting the test data part, which can deviate from the expected format by receiving devices, and cannot generate secure telegrams at the user level when using coded monoprocessors, leading to potential errors and incorrect reactions.
Innovation Solution
A method where original user and test data are stored in a secure software environment, with copies generated outside, allowing for comparison to ensure accuracy, and enabling the creation of a secure telegram with user data and test data parts that can be verified at the user level, even with coded monoprocessors, by comparing data copies within the secure environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the test data part format is predetermined in secure telegram generation systems, then security and reliability are improved, but flexibility and adaptability to different receiving devices deteriorate
Solution Approach 1:
The patent implements dynamic format selection for the test data part, allowing the format to be changed based on the receiving device's capabilities. The system determines the expected format from format information and configures the test data part accordingly, transforming a static predetermined format into a dynamic adaptable format that maintains security while improving flexibility.
2Reliability
If secure telegrams are generated using coded monoprocessors, then security is improved, but the ability to generate secure telegrams at the user level deteriorates
Solution Approach 1:
The patent introduces an intermediary mechanism where format information acts as a mediator between the coded monoprocessor and the user level. The format information enables the user level to understand and verify the test data part structure without requiring direct access to the coded processing environment, thus bridging the gap between secure generation and user-level accessibility.
Solution Approach 2:
The patent uses copying of data between secure and non-secure environments. The test data part is generated or verified at the user level by copying and comparing data structures, allowing secure telegram generation capabilities to be effectively extended to the user level through data replication and comparison techniques.
3Ease of operation
If data processing occurs in a non-secure software environment, then ease of operation and flexibility are improved, but error detection and security deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where the test data part serves as a verification component that provides feedback on the correctness of the secure telegram generation. The receiving device uses the test data part to verify the integrity and correctness of the transmitted data, creating a feedback loop that enhances error detection while maintaining the flexibility of non-secure environment processing.
