Integrated Security Module for Remote Input Data Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for securing data transmitted from input devices to processing components are limited, as they require the input device to be co-located within the same security boundary, which is not feasible when data traverses insecure mediums like wireless networks.
Innovation Solution
Integrating a security module into the input device to generate and secure data using asymmetric or symmetric keys, establishing a secure communication channel over insecure mediums, allowing secure data transmission to remote processing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the input device is placed within the security boundary of the processing component, then data security is improved, but the adaptability of the input device location deteriorates
Solution Approach 1:
A security module is introduced as an intermediary component integrated into the input device. This security module establishes encrypted communication channels between the input device and processing component, allowing secure data transmission without requiring the input device to be physically located within the processing component's security boundary. The security module acts as a mediator that protects data in transit over insecure mediums.
Solution Approach 2:
The system is segmented into distinct functional components: the input device with its integrated security module, and the remote processing component. This segmentation allows each component to operate independently while maintaining security through cryptographic protocols, enabling the input device to be located remotely while still providing secure data transmission.
2Reliability
If the input device is co-located with the processing component, then data security is improved, but the ease of operation deteriorates
Solution Approach 1:
The security module serves as an intermediary that enables secure remote operation. Users can operate input devices from convenient locations while the security module ensures that data transmitted to the processing component remains protected, thus maintaining both security and ease of operation.
3Adaptability or versatility
If a security module is integrated into the input device, then adaptability of input device location is improved, but device complexity increases
Solution Approach 1:
The security module is merged with the input device to form an integrated unit. This combination allows the input device to independently perform cryptographic operations and establish secure communication channels without requiring separate security infrastructure, thus improving location adaptability while managing complexity through integration.

AI summary
An input device with an integrated security module communicates with a processing component over an insecure medium. The insecure medium may be a wireless network, software stack, or the like. According to one embodiment, the security module is integrated into an existing chip of the input device. Data generated by the input device is encoded and/or authenticated by the security module prior its transmission to the processing device. The processing device receives the input data and processes it within its own security boundary for providing selected services or information to a user or application associated with the input device.
