    摘要： A method and apparatus for anticipating communication interruption. If, during an established call between two communication devices, a telecommunication device determines that a communication link to one of the devices will be interrupted, either temporarily or permanently, the device predicts the interruption in the communication link. The device may send a message, as pre-determined by at least one of the communication device, to the communication device of the predicted or pending call drop or interruption. After the interruption the previously established call is resumed. If a reconnection attempt is appropriate, then the device will attempt to reconnect to the dropped device. If a reconnection attempt is not appropriate, or if the reconnection attempt is unsuccessful, the non-dropped communication device is connected, as predetermined by either of the communication devices, to an appropriate connection, such as, to a voice mail. If the reconnection attempt is successful, the call between the two communication devices is re-established.

    摘要： The present invention permits a network service provider to detect an operational condition—such as congestion—in a packet-switched network and to alleviate such congestion by providing customer incentives to avoid use of the network. The detection mechanism triggers an incentive such as the modification of the user's access charges and the customer can be immediately notified of either the occurrence of the congestion or of information regarding the incentive. Usage of the network during congested periods can be deterred by imposing additional access charges during such periods—similarly, customers can be given a discount to encourage usage during periods of low congestion. An incentive schedule can be tailored to dynamically change the usage patterns of the customers of the network to accommodate the operational conditions in the network. The present invention has application in the Internet, where a detection/notification mechanism, for example, can be implemented in a network node such as a router or in a network endpoint such as a client machine or a proxy or mail server.

    摘要： Encryption with keys that form an Abelian group are used in combination with a semi-trusted party that converts queries that are encrypted with the key of a querier to queries that are encrypted with the key of the encrypted database, without knowing the actual keys. In an illustrative embodiment, encryption is done with Bloom filters that employ Pohlig-Hellman encryption. Since the querier's key is not divulged, neither the semi-trusted party nor the publisher of the database can see the original queries. Provision can be made for fourth party “warrant servers”, as well as “censorship sets” that limit the data to be shared.

    摘要翻译： 与形成Abelian组的密钥的加密与半信任方结合使用，它将使用查询器的密钥加密的查询转换为使用加密数据库的密钥加密的查询，而不知道实际的密钥。 在说明性实施例中，使用采用Pohlig-Hellman加密的布隆过滤器进行加密。 由于查询器的密钥未被泄露，所以半信任方和数据库的发布者都不能看到原始查询。 可以规定第四方“认股权证服务器”以及限制数据共享的“审查集”。

    摘要： A method and apparatus for a implementing a distributed firewall is described. A packet filter processor receives a packet sent from a first device to a second device. The packet filter processor authenticates an identifier for the packet. For example, authentication could be performed using a cryptographically-verifiable identifier. The packet filter processor determines whether to send the packet to the second device, based on the authentication and a set of policy rules. The packet filter processor sends the packet to the second device in accordance with the determination.
