    • A system for providing cost effective, secure key exchange from at least one first device to at least one second device through at least one proxy server is provided. The system includes a first key exchange message from the at least one first device to the at least one second device via the at least one proxy server. A second key exchange message from the at least one second device to the at least one first device via a media stream of the Internet is required to complete the computation of the session key. A method of securing a communication system is also set forth. The method includes the steps of providing a routing device for identifying a subscriber, and providing a master key exchange session, the master key exchange session including a key k to find a subscriber and a nonce r to answer a query to the subscriber, wherein the master key exchange session includes both the key k and the nonce r.
    • 提供了一种用于通过至少一个代理服务器从至少一个第一设备向至少一个第二设备提供成本有效的安全密钥交换的系统。 该系统包括经由至少一个代理服务器从至少一个第一设备到至少一个第二设备的第一密钥交换消息。 需要经由互联网的媒体流从至少一个第二设备到至少一个第一设备的第二密钥交换消息来完成对话密钥的计算。 还提出了一种保护通信系统的方法。 该方法包括以下步骤:提供用于识别订户的路由​​设备,以及提供主密钥交换会话,所述主密钥交换会话包括密钥k以找到订户并且随机地向订户回答查询,其中所述 主密钥交换会话包括密钥k和随机数r。
