摘要： Techniques are disclosed for use in securing communications in environments comprising hybrid communication systems. For example, a method comprises, in a hybrid communication system wherein at least one computing device is configured to selectively operate in a first communication mode or a second communication mode, preventing the at least one computing device from completing an attachment process in the first communication mode when it is determined that authentication data being used to authenticate the at least one computing device in the first communication mode was generated for an authentication process in the second communication mode.

摘要： A tracker node verifies content possession by a peer node in a peer-to-peer content distribution system. Upon receiving an announcement that a peer node claims to possess a content item, the tracker node in one embodiment obtains the content item, selects a random portion of the content item; formulates a challenge based on the random portion of the content item and determines an expected challenge response. The challenge may comprise, for example, a request for a hash of the random portion (or alternatively, a hash of the random portion and a random seed value). The tracker node issues the challenge to the announcing node and verifies the announcing node's possession of the content item if the challenge response from the announcing node matches the expected challenge response.

摘要： Techniques are disclosed for making one or more computing devices in a communication network aware of a public warning system security policy of at least one entity. In one example, a method comprises the following steps. An indicator of a public warning system security policy of at least one entity is associated with a control plane message. The control plane message, with the indicator of the public warning system security policy of the at least one entity, is generated by a first computing device of a communication network. The first computing device transmits the control plane message, with the indicator of the public warning system security policy of the at least one entity, to a second computing device of the communication network. The second computing device is made aware of the public warning system security policy of the at least one entity.

摘要： A method for securing at least one message transferred in a communication system from a first computing device to a second computing device in a peer-to-peer manner. At the first computing device, an identity based authenticated key exchange session is established with a third computing device operating as a peer authenticator. The identity based authenticated key exchange session has an identity based authenticated session key associated therewith. The first computing device obtains from the third computing device a random key component of the second computing device, wherein the random key component of the second computing device is encrypted by the third computing device using the identity based authenticated session key prior to sending the random key component of the second computing device to the first computing device. A peer-to-peer messaging key is computed at the first computing device using the random key component of the second computing device.

摘要： In conjunction with establishment of a session between an access network and user equipment of a communication system, session-specific information is transmitted from the access network to the user equipment. The session-specific information transmitted from the access network to the user equipment comprises information to be utilized in an authentication protocol carried out between the user equipment and an authentication server of the system. For example, the session-specific information transmitted from the access network to the user equipment may comprise an identifier of a gateway coupled between the access network and the authentication server.

摘要： The present invention provides a method of route optimization involving a first mobile device associated with a first home gateway. One embodiment of the method is implemented in a first mobility forwarding entity and includes registering the first mobile device at the first mobility forwarding entity. The first mobile device is registered using a session key included in a registration message transmitted by the first mobile device. The embodiment also includes establishing a secure route between the first mobility forwarding entity and a terminating node using the session key. The secure route bypasses the first home gateway.
