Device-Level Security Layer for Remote Control Data Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission systems for remotely controlled devices over networks are vulnerable to unauthorized data manipulation and lack security measures at the device level, particularly before data is encrypted by microcontrollers, making them susceptible to attacks that can render devices inoperative or lead to life-threatening scenarios.
Innovation Solution
Implementing a security layer at the data converter within electronic devices that secures data prior to transmission and verifies the validity of control commands through two-way authentication, ensuring data integrity and trustworthiness by applying security protocols such as encryption, authentication, and validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is transmitted over networks without security measures at the device level, then ease of operation is improved, but reliability deteriorates due to vulnerability to unauthorized data manipulation
Solution Approach 1:
The patent applies preliminary action by implementing security measures at the device level before data leaves the device. Security protocols including encryption, authentication, and data validation are executed at the source (device level) prior to network transmission, ensuring data integrity and preventing unauthorized manipulation before the data enters the network environment.
2Reliability
If security measures are applied at the device level prior to transmission, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the security functionality into distinct modular components: encryption modules, authentication modules, and data validation modules. Each security function operates as an independent module within the device, allowing for targeted implementation and management of security measures without requiring complete system redesign.
Solution Approach 2:
The patent applies universality by designing security protocols that can be applied across multiple device types and communication scenarios. The security framework is implemented as a universal layer that works with various data formats and transmission protocols, allowing the same security infrastructure to protect diverse devices including sensors, actuators, and control systems.
3Device complexity
If data is not secured at the point of generation, then device complexity is reduced, but loss of information increases due to potential data manipulation
Solution Approach 1:
The patent applies preliminary action by implementing data validation and authentication checks at the point of data generation before the data is transmitted or processed further. This preliminary verification ensures that only valid, authentic data enters the system, preventing corrupted or manipulated data from propagating through the network and causing information loss.
