Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RF computer networking equipment is inefficient and costly in providing doubly encrypted data, as it requires multiple devices and separate tunnels for secure and unsecure traffic, leading to significant bandwidth overhead.
Innovation Solution
A data transmission network device with an integrated encryption module and RF transceiver that performs double encryption, allowing for efficient modulation of encrypted data onto an RF signal while enabling the transmission of both secure and unsecure data through a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple devices (modems, switches, routers) and separate secure tunnels are used to provide doubly encrypted data, then security standards compliance is achieved, but bandwidth efficiency deteriorates with up to 30% overhead
Solution Approach 1:
The patent combines multiple network functions (modem, switch, router, encryption devices) into a single integrated network device. This consolidation allows the device to perform double encryption internally without requiring separate secure tunnels, thereby eliminating the 30% bandwidth overhead associated with traditional multi-device architectures while maintaining security compliance.
Solution Approach 2:
The integrated network device performs multiple functions simultaneously: it acts as a modem, switch, router, and double encryption device all in one unit. This multi-functionality enables the device to handle both encrypted and unencrypted traffic efficiently without requiring separate infrastructure, resolving the contradiction between security requirements and bandwidth efficiency.
2Reliability
If encryption devices are placed at both ends of the enclave to provide secure network tunnels, then data security is improved, but device complexity and cost increase
Solution Approach 1:
Instead of placing separate encryption devices at both ends of the enclave, the patent integrates encryption functionality directly into the network device itself. This single-device solution performs double encryption internally, eliminating the need for additional encryption devices and reducing overall system complexity while maintaining robust data security.
3Reliability
If separate unsecure network tunnels are required for unsecure traffic, then traffic security is maintained, but network infrastructure complexity increases
Solution Approach 1:
The integrated network device provides universal handling of both encrypted and unencrypted traffic through its encryption module, which can be selectively enabled or disabled. This eliminates the need for separate unsecure network tunnels while maintaining traffic security when needed, thereby simplifying the overall network infrastructure.

Function Achieved in This Case
This solution enhances spectral efficiency and reduces costs by providing a single, cost-effective device for secure RF networking links, capable of transmitting both encrypted and unencrypted data with minimal bandwidth overhead.
Implementation Method 1
The RF transceiver is configured to generate an RF signal such that the second encrypted data is modulated onto the RF signal
Data Source
AI summary
Embodiments of a data transmission network device and methods of operating the same are disclosed. In one embodiment, the data transmission network device includes an encryption module and an RF transceiver. The encryption module is configured to receive data and encrypt the data so as to generate first encrypted data. The encryption module then encrypts the first encrypted data so as to generate second encrypted data. The RF transceiver is configured to generate an RF signal such that the second encrypted data is modulated onto the RF signal. By providing the double encryption in a single device, the data transmission network device has greater spectral efficiency and is a much more cost-effective solution than what is currently provided in the market. Furthermore, the encryption module can be disabled so that unsecure data can also be transmitted via the data transmission network device.
