Conference Control With Cryptographic Device Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in verifying the authenticity of participants in audio and video conferences, particularly in the context of deep faked identities, leading to security risks and impersonation attacks.
Innovation Solution
Implementing a method and electronic device that control conferences by setting up requirements, verifying device configurations, and allowing only participants with valid setups, such as specific audio and video devices, to join, using cryptographic keys and digital signatures to authenticate devices and reduce the risk of deep fake attacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional communication systems allow participants to join conferences without strict device verification, then ease of operation is improved, but security and reliability deteriorate due to impersonation attacks and deep fake risks
Solution Approach 1:
The system performs preliminary verification of device configurations before allowing conference participation. The host device receives and validates device configuration data from participating devices, checking cryptographic signatures and device identifiers in advance, so that only verified devices are admitted to the conference, thus ensuring security before the actual conference begins
Solution Approach 2:
The host device acts as an intermediary between participating devices and the conference system. It mediates the verification process by receiving device configuration data, validating cryptographic signatures, checking device identifiers against a whitelist, and controlling admission based on verification results, thereby enabling secure conference entry without requiring participants to directly trust each other
2Reliability
If device configuration verification is implemented for all participants, then security against deep fake attacks is improved, but device complexity increases due to cryptographic key management and signature verification
Solution Approach 1:
The complex cryptographic verification operations are extracted from individual participant devices and centralized in the host device. Participating devices only need to provide their device configuration data and cryptographic signatures, while the host device performs the heavy lifting of signature verification, device identifier validation, and whitelist checking, thus reducing the complexity burden on participant devices
Solution Approach 2:
The system implements verification at the host device level rather than requiring full verification capabilities in every participant device. This partial action approach concentrates the complex cryptographic operations in one location (the host) while allowing other devices to participate with simpler functionality, achieving high security without requiring all devices to be equally complex

AI summary
An electronic device and a method of controlling a conference between a first communication device and a second communication device is disclosed, the method comprising setting up a conference with associated conference requirements; receiving a participation request to participate in the conference from the second communication device, the participation request comprising a device configuration indicative of one or more devices associated with a participant in the conference; determining whether the device configuration satisfies the conference requirements; and in accordance with the device configuration satisfying the conference requirements, including the second communication device in the conference.
