摘要： In one embodiment, a method includes automatically detecting occurrence of an event at an endpoint that suggests checking whether a public safety answering point (PSAP) currently associated with the endpoint is correctly associated with the endpoint. The method further includes, in response to the occurrence of the event, automatically prompting through the endpoint a user to provide input indicating whether data identifying a current location of the endpoint is correct. The method further includes receiving input from the user through the endpoint indicating whether the data is correct and, if the input from the user indicates that the data is not correct, automatically initiating an update of the data to correctly identify the current location of the endpoint.

摘要： In one embodiment, a method for presence-based management in a communication network includes, using IM, discovering one or more network devices in a communication network. The network devices couple two or more endpoints to each other and enable communication between a first one of the endpoints and one or more second ones of the endpoints. The method also includes, using IM, obtaining presence information on the discovered network devices from the discovered network devices and, using the presence information on the discovered network devices from the discovered network devices, maintaining presence data associated with the discovered network devices.

摘要： A system may generate from a first value, based on rounding information, a first security key that matches a second security key whenever the first value and a second value from which the second security key is generated differ by less than a non-zero predetermined amount. The second security key may be generated from the second value rounded to a multiple of a rounding interval that is nearest to the second value. The rounding information may include a rounding direction indication. The rounding direction indication may indicate the direction in which the second value is rounded to the multiple of the rounding interval nearest to the second value.

摘要： A system may protect against Sybil attacks on a peer-to-peer (P2P) network based on each one the nodes in the P2P network being identified by a corresponding certificate. In particular, a node may receive a license key, where the license key is evidence of a purchased product license. The node may transmit a message included in the license key to a certificate authority. The node may receive a certificate from the certificate authority in response to authentication of the message. The node may be identified in the P2P network with a node identifier included in the certificate.
摘要翻译： 基于P2P网络中的每个节点由对应的证书标识的系统可以防止对等（P2P）网络上的Sybil攻击。 特别地，节点可以接收许可证密钥，其中许可证密钥是购买的产品许可证的证据。 节点可以将许可证密钥中包括的消息发送到证书颁发机构。 节点可以响应于消息的认证从证书颁发机构接收证书。 节点可以在P2P网络中被识别，其中包括在证书中的节点标识符。

摘要： An authentication agent may cryptographically identify a remote endpoint that sent a media initialization message even though intermediate devices may modify certain fields in the message after a signature is inserted. The originating endpoint's agent may create the signature over some fields of the message using an enterprise network's private key. The agent may insert the signature into the message and send the message to a recipient endpoint's authentication agent. The recipient agent may verify the signature, receive a certificate including a second public key, and challenge the identity of the originating endpoint in order to confirm that identity. This challenge may request a confirmation that the originating endpoint knows the private key corresponding to the second public key and may occur while running encrypted media at the endpoints. After the originating endpoint is authenticated, the endpoints may exchange encrypted and/or unencrypted media.
摘要翻译： 认证代理可以密码地标识发送媒体初始化消息的远程端点，即使中间设备可以在签名被插入之后修改消息中的某些字段。 始发端点的代理可以使用企业网络的私钥在消息的某些字段上创建签名。 代理可以将签名插入消息中，并将消息发送到接收方端点的认证代理。 接收方代理可以验证签名，接收包括第二公钥的证书，并且对发起端点的身份进行质询以便确认该身份。 该挑战可以请求确认始发端点知道与第二公钥相对应的私钥，并且可能在端点处运行加密媒体时发生。 在始发端点被认证之后，端点可以交换加密和/或未加密的媒体。
