Title:
A METHOD FOR THE ACHIEVEMENT OF THE MESSAGE TRANSMISSION IN THE H323 SYSTEM
Document Type and Number:
WIPO Patent Application WO/2005/079013
Kind Code:
A1
Abstract:
The invention provides a method for the achievement of the message transmission in the 323 system. The procedure negotiation for message transmission is made by using the gatekeeper route, and it determines the information required when it certificates directly the message transmission using direct route module between the different terminals, and ensures the security for transmits the message directly between the different terminals by mean of the information required for determining the certification by using the negotiation. The invention can ensure the required security of the information, because the identification and the privacy technology for the 323 system was described in the 323 protocol of the ITU-T, and provides the security service for the gatekeeper route message transmission. This invention cannot effect the performance of the middle entities in the H323 system by using the cryptographic key switching technology based on the Diffie-Hellman. The invention makes the retractility for the symmetry cryptograph system better by mean of the negotiation manner. The invention defines and improves the security frame of the message transmission in the 323 system under the direct route module; thereby, it can achieve the purpose that improve the security of the H323 system.
