Conference Data Encryption With Automated Key Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional online conference systems lack adequate security measures to protect conference content from unauthorized access and leakage, especially in important conferences requiring higher security levels.
Innovation Solution
A conference data transmission method involving a security enhancement module that encrypts conference data with a conference key, transmitted through a cloud platform, ensuring secure communication between a conference transmission device and a conference client.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conference data is transmitted in plaintext form, then transmission simplicity is maintained, but security is compromised and content is easily attacked or leaked
Solution Approach 1:
The patent applies preliminary action by pre-distributing encryption keys to participants before the conference starts. The key management server generates and distributes conference keys to all participants in advance, so that when the conference begins, encryption can immediately occur without adding complexity to the transmission process itself
Solution Approach 2:
The patent introduces a key management server as an intermediary between participants. This mediator handles key generation, distribution, and management, thereby isolating the encryption complexity from the actual conference transmission device and participants, making the system both secure and simple to use
2Reliability
If encryption is implemented for all conference data, then security is improved, but transmission efficiency and processing speed are reduced
Solution Approach 1:
The patent applies local quality by selectively encrypting only sensitive conference data such as chat messages and shared files, while leaving other data types unencrypted. The key management server determines which data requires encryption based on its sensitivity, thereby maintaining security for critical information while preserving transmission efficiency for non-sensitive data
Solution Approach 2:
The patent changes the encryption parameter from 'always encrypt' to 'encrypt based on data type and sensitivity'. The key management server dynamically adjusts encryption application based on the characteristics of the data being transmitted, optimizing the balance between security and efficiency
3Reliability
If complex key management systems are introduced, then security is enhanced, but ease of operation is reduced and user burden increases
Solution Approach 1:
The patent applies self-service by enabling participants to automatically receive and manage their encryption keys through the key management server. Participants simply need to join the conference; the system automatically handles key distribution, renewal, and revocation without requiring users to manually manage cryptographic materials
Solution Approach 2:
The key management server acts as an intermediary that shields users from cryptographic complexity. It handles all key management operations including generation, distribution, storage, and revocation, allowing participants to focus on conference participation rather than security management
4Reliability
If encryption keys are distributed to all participants, then secure communication is enabled, but key management complexity and security risks increase
Solution Approach 1:
The patent implements feedback mechanisms where the key management server continuously monitors conference participation status and automatically adjusts key distribution. When participants join or leave, the server detects this feedback and accordingly distributes or revokes keys, maintaining secure communication while simplifying key management through automated response to system state changes

AI summary
A conference data transmission method, an apparatus and a system, an electronic device and a readable medium are disclosed, belong to the technical field of computers and can avoid the illegal intrusion in the prior art. The conference data transmission method includes: receiving unencrypted first conference data transmitted by a conference transmission device in a case where an identity verification of a participant is passed; acquiring a conference key corresponding to the first conference data, and encrypting the first conference data through the conference key, to obtain encrypted second conference data; and transmitting the encrypted second conference data to the conference transmission device, so that the conference transmission device provides the encrypted second conference data to a conference client through a cloud platform. The present disclosure can improve the security of conference data transmission and avoid the problem of cracking in the data transmission process.
