Secure Room Control Isolator for Video Teleconferencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video teleconferencing systems lack secure control mechanisms that meet the security requirements for multi-network systems, particularly in preventing unauthorized access to sensitive information within the codec, which can compromise the confidentiality of the video teleconferencing traffic and room collateral information.
Innovation Solution
A secure room control isolator is introduced, which is coupled between the video teleconferencing room controller and the codec, allowing only control commands to flow from the controller to the codec while restricting any information return, using a serial link air gap isolator to prevent unauthorized access and filtering commands to ensure only legitimate, non-security-violating actions are performed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the room controller is connected directly to the codec to enable control commands, then the ease of operation is improved, but the security vulnerability increases allowing unauthorized access to sensitive information
Solution Approach 1:
A secure room control isolator is introduced as an intermediary device between the room controller and the codec. This isolator permits only control commands to flow from the controller to the codec while blocking all information return paths, thereby maintaining operational ease while preventing unauthorized access to sensitive information in the codec.
2Measurement precision
If the room controller can access information from the codec, then the measurement precision of system status is improved, but the loss of information security increases
Solution Approach 1:
The communication interface is segmented into separate control command path and status information path. The isolator allows control commands to pass through to the codec while separately managing status information return paths, enabling precise system status measurement without compromising the confidentiality of VTC traffic and room information.
3Adaptability or versatility
If multi-network VTC systems are deployed to provide access to multiple networks, then the adaptability is improved, but the device complexity increases requiring additional security measures
Solution Approach 1:
The secure room control isolator provides universal security protection across multiple network configurations. It maintains a single simplified interface that works whether the codec is connected to classified or unclassified networks, providing consistent security control without requiring separate complex security configurations for each network type.

AI summary
Method, system, and computer program product example embodiments of the invention are disclosed to provide a secure room control isolator for a multi-network secure video teleconferencing room that meets the DISA and other standard security requirements. An example embodiment of the invention is a secure room control isolator coupled between a video teleconferencing room controller and a codec, to enable control commands to be sent from the room controller to the codec, but which permits only status information to be returned from the codec to the room controller. In this manner, classified information in the codec cannot be accessed by the room controller.
