摘要： A method and apparatus for sending a first secured media stream having a payload via an intermediate node. The intermediate node receives from a sender the first secured media stream. An end-to-end context identifier and a hop-by-hop context identifier are determined for the first secured media stream, where the hop-by-hop context identifier relates to the intermediate node and the end-to-end identifier relates to the sender. A second secured media stream is generated, which includes at least the payload of the first secured media stream and the context identifiers to identify the first secured media stream. The second secured media stream is sent to a receiving node, and the context identifiers are also sent to the receiving node. The context identifiers are usable by the receiving node to recover the first secured media stream.

摘要： A method and arrangement is disclosed for managing session keys for secure communication between a first and at least a second user device in a communications network. The method is characterized being independent of what type of credential each user device implements for security operations. A first user receives from a first key management server keying information and a voucher and generates a first session key. The voucher is forwarded to at least a responding user device that, with support from a second key management server communicating with the first key management server, resolves the voucher and determines a second session keys. First and second session keys are, thereafter, used for secure communication. In one embodiment the communication traverses an intermediary whereby first and second session keys protect communication with respective leg to intermediary.

摘要： A method and apparatus for sending protected media data from a data source node to a client node via an intermediate node. The data source node establishes a first hop-by-hop key to be shared with the intermediate node and an end-to-end key to be shared with the client node. A single security protocol instance is configured and used to trans-protocol form data from a media stream into transformed data using the keys. The transformed data is then sent to the intermediate node. The intermediate node uses the first hop-by-hop key to apply a security processing to the transformed data, and establishes a second hop-by-hop key with the client node. A second transformation is performed on the transformed data using the second hop-by-hop key to produce further transformed media data, which is then sent to the client node. At the client node a single security protocol instance is configured with the second hop-by-hop key and the end-to-end key, which are used to apply further security processing to the transformed media data.

摘要： Methods and apparatuses in a client terminal (400) and a web server (402) for enabling safe communication between said terminal and server. When the terminal obtains a web page from the server in a session, the terminal creates a context-specific key, Ks_NAF′, based on one or more context parameters, P1, . . . Pn, pertaining to said session and/or web page. The terminal then indicates the context-specific key in a login request to the server, and the server determines a context-specific key, Ks_NAF′, in the same manner to verify the client if the context-specific key determined in the web server matches the context-specific key received from the client terminal. The context-specific key is thus bound to and valid for the present context or session only and cannot be used in other contexts or sessions.

摘要： A method and apparatus for sending protected data from a sender unit to a receiver unit via an intermediate unit. A Transfer Init message that contains a ticket associated with the receiver unit is sent from the intermediate unit to the sender unit. The intermediate unit then receives a transfer response message from the sender unit, and also data which has been protected using at least one security key associated with the ticket and obtained from a Key Management Server. A message is sent to the receiver unit, the message including information required for security processing of the protected data. The protected data is then sent to the receiver unit, allowing the receiver unit to access the protected data.

摘要： There is described herein a device (101) for communicating with a network. The device (101) comprises a communications unit for receiving data, a notification device for providing a notification to a user, and a control unit for controlling the operation of the communications unit and notification unit. The communications unit is configured to receive an information message (110, 112, 115), and to receive security authentication data (110, 112, 115) associated with the information message if such security authentication data is available. The control unit is configured to operate in a first or second configuration. In the first configuration it ignores the security authentication data, (111, 113), and instructs the notification unit to convey the notification to the user. In the second configuration, it verifies the information message (116) on the basis of the security authentication data and instructs the notification unit to convey the notification to the user if the verification is successful. The communications unit is configured to receive a configuration message (114) indicating the configuration in which the control unit should operate, and the control unit is configured to change configuration if the indicated configuration is different to the current configuration.
