Abstract
Provided are a system and method for distributing a group key for a video conference using a one-time password in a video conference system. The method includes: when a video terminal is required to participate in a video conference, generating a challenge value and a response value corresponding to the video terminal; encrypting a group key corresponding to the video conference with the response value, and transmitting the encrypted group key and the challenge value to the video terminal; and causing the video terminal to participate in the video conference in response to an acknowledgement message from the video terminal. This results in high user friendliness and high-level security.

A method for distributing a group key in a video conference system, comprising:
- when a video terminal is required to participate in a video conference, generating a challenge value and a response value corresponding to the video terminal;
- encrypting a group key corresponding to the video conference with the response value, and transmitting the encrypted group key and the challenge value to the video terminal;
- and
- causing the video terminal to participate in the video conference in response to an acknowledgement message from the video terminal.
A system for distributing a group key in a video conference system, comprising:
- a one-time password module for generating a challenge value and a response value corresponding to a video terminal;
- and
- a multipointing control unit for, when the video terminal is required to participate in a video conference, encrypting a group key corresponding to the video conference with the response value, transmitting the encrypted group key and the challenge value to the video terminal, and causing the video terminal to participate in the video conference in response to an acknowledgement message from the video terminal.
A method for distributing a group key in a video conference system, comprising:
- when a video terminal is required to participate in a video conference, generating a one-time password at a specific time based on synchronization time information with the video terminal;
- encrypting a group key corresponding to the video conference with the generated one-time password and transmitting the encrypted group key to the video terminal;
- and
- causing the video terminal to participate in the video conference in response to an acknowledgement message from the video terminal.
