摘要： The present invention provides a method of data path switching. Embodiments of the method include transmitting a packet from a node in a communication system during hand off of a mobile node from a source access network to a target access network. The packet includes an end marker that indicates that the packet is the last packet to be transmitted during the hand off over a source link between the mobile node and an anchor node via the source access network during the hand off. Embodiments of the method also include switching, at the node, a transmission data path from the source link to a target link between the mobile node and the anchor node via the target access network following transmission of the packet including the end marker.

摘要： A method is provided for establishing a backup interface among multiple interfaces serving a mobile node, for a handover that is undetectable in advance. The invention methodology operates to cause a Foreign Agent associated with the multiple interfaces to keep a binding record of each of the multiple interfaces for which the mobile node has successfully completed the registration process. A novel Mobile IP extension is also added to facilitate the backup FA binding of the invention methodology.

摘要： The secure management of encryption keys is obtained by preventing external access thereto and ensuring that the keys do not leave an encryption unit in their original form. This result is obtained via a facility which (a) generates a unique device encryption key and at least one program encryption key, (b) encrypts the program encryption key using the device encryption key, and (c) stores the result in local memory. Thereafter, responsive to receipt of an indication to encrypt data, the program encryption key is retrieved from memory and is decrypted using the unique device encryption key. The data is then encrypted using the decrypted program encryption key and the encrypted data is stored in a server for distribution to a user who enters a request for the data. When there is a need to transport the latter key to another element, then the program key is encrypted using a symmetrical encryption key that the facility shares with the other element and the result is supplied to that element. The element then decrypts the encrypted program key using its own version of the symmetrical key.

摘要： A security node disposed in the telecommunications network connecting calling and called parties transforms information (which can be voice, data, facsimile, video and other types of calls or messages) encrypted in a first format to (a) encrypted information in a different format or to (b) non-encrypted information, and vice-versa. The node is accessible from any location connected to the network. By routing calls or messages originated by the calling party and destined for the called party via the security node, and providing appropriate control signals to the node, the information may be encrypted only over a portion of the transmission path between the parties, and clear over the remainder of the transmission path. Alternatively, the information may be encrypted in different portions of the path using different encryption algorithms. This arrangement enables the parties to obtain relatively secure communications even if only one party has a security device at the originating or terminating end, or if the parties have security devices using different handshaking protocols and encryption algorithms.
摘要翻译：设置在连接主叫和被叫方的电信网络中的安全节点将以第一格式加密的信息（可以是语音，数据，传真，视频和其他类型的呼叫或消息）转换为（a）不同格式的加密信息，到（b）非加密信息，反之亦然。该节点可从连接到网络的任何位置访问。通过路由由主叫方发起并通过安全节点发往被叫方的呼叫或消息，并向节点提供适当的控制信号，该信息可以仅在双方之间的传输路径的一部分上被加密，并且清除传输路径的其余部分。或者，可以使用不同的加密算法在路径的不同部分中加密该信息。这种安排使得即使只有一方在始发或终端具有安全设备，或者如果各方具有使用不同的握手协议和加密算法的安全设备，则各方可以获得相对安全的通信。

摘要： In a communication system in which a node may communicate over insecure channels with any of a plurality of terminals and may pass messages from any of the terminals to any other of the terminals, communication is secured by computing a first cryptovariable from information associated with certificates exchanged between the node and a terminal, computing a second cryptovariable from a prior-art public key exchange, and computing a session cryptovariable as a function of the first and second cryptovariables. This can be done asymmetrically, enabling a terminal to verify the security of an unattended node.
摘要翻译：在其中节点可以通过不安全信道与多个终端中的任何一个进行通信的通信系统中，并且可以将消息从任何终端传递到终端的任何终端，通过从与交换的证书相关联的信息计算第一密码变量来保证通信在所述节点和终端之间，计算来自现有公共密钥交换的第二密码变量，以及根据所述第一和第二密码变量计算会话密码变量。这可以不对称地完成，使得终端能够验证无人值守节点的安全性。
