    • The present invention provides a method for providing message transmission in H.323 communication system. The method includes: the first endpoint and second endpoint confirming authentication information through a GK; according to said authentication information, the first endpoint and second endpoint exchanging message directly. Since H.235 protocol of ITU-T describes the authentication and privacy technique used in H.323 systems and provides security service for message transmission in GK-routed model, the present invention can guarantee the security of the authentication information. The functions of middle entities need not to be modified for applying the method provided by the present invention because Diffie-Hellman key exchange technology is adopted in this method. The present invention increases the network scalability of the symmetric key system by adopting negotiation mode. The present invention designates and improves the security framework of message transmission in direct-routed model of H.323 system, thereby improving the security of H.323 system.
    • 本发明提供了一种在H.323通信系统中提供消息传输的方法。 该方法包括:第一端点和第二端点通过GK确认认证信息; 根据所述验证信息,第一端点和第二端点直接交换消息。 由于ITU-T的H.235协议描述了H.323系统中使用的认证和隐私技术,并为GK路由模型中的消息传输提供安全服务,本发明可以保证认证信息的安全性。 由于本方法采用Diffie-Hellman密钥交换技术,中间实体的功能不需要修改,适用于本发明提供的方法。 本发明通过采用协商模式提高对称密钥系统的网络可扩展性。 本发明指定并改进了H.323系统直接路由模型中消息传输的安全框架,从而提高了H.323系统的安全性。
