Abstract
A method of providing secured teleconference in a distributed teleconference system including providing one or more servers interconnected in a distributed structure, providing at least two participants which include at least one speaker; where each participant is a listener. Each participant is connected to a server and is associated with a secured teleconferencing application, encrypting the data that is created by the speaker's application, building an authentication tag by the speaker application, transmitting a media packet by the speaker's application to the connected server, checking authentication tag validity by each server that receives a media packet and selectively distributing the media packet if the authentication tag check succeeded and checking authentication tag validity by each listener that receives a media packet and decryption of the encrypted data provided that the authentication tag validity check succeeded.
