摘要： A method apparatus for storing and forwarding media data in a communication network. An intermediate node disposed between a media data source node and a client node receives encrypted media data packets from the media data source node. The intermediate node stores the received media data packets in a memory for later sending to the client node, and adjusts fields in the original header of each stored media data packet to create modified media data packets having a modified header, and sends adjustment information to the client node. The adjustment information allows the client node to recreate the original headers from the modified headers, before decrypting the encrypted media packets with keying materials already sent between the media data source node and the client node. The modified media data packets are then sent to the client node for decryption. This allows the intermediate node to “store and forward” SRTP data without being able to access the encrypted data content.
摘要翻译：一种在通信网络中存储和转发媒体数据的方法装置。设置在媒体数据源节点和客户端节点之间的中间节点从媒体数据源节点接收加密的媒体数据分组。中间节点将接收到的媒体数据分组存储在存储器中用于随后发送到客户端节点，并且调整每个存储的媒体数据分组的原始报头中的字段以创建具有修改的报头的修改的媒体数据分组，并将调整信息发送到客户端节点。调整信息允许客户端节点在已经在媒体数据源节点和客户机节点之间发送的密钥材料解密加密的媒体分组之前，从修改的报头重新创建原始报头。然后将经修改的媒体数据分组发送到客户端节点进行解密。这允许中间节点“存储和转发”SRTP数据，而不能访问加密的数据内容。

摘要： When a mobile terminal (10), having a basic identity module (12) operative according to a first security standard, initiates a service access, the home network (30) determines whether the mobile terminal has an executable program (14) configured to interact with the basic identity module for emulating an identity module according to the second security standard. If it is concluded that the mobile terminal has such an executable program, a security algorithm is executed at the home network (30) to provide security data according to the second security standard. At least part of these security data are then transferred, transparently to a visited network (20), to the mobile terminal (10). On the mobile terminal side, the executable program (14) is executed for emulating an identity module according to the second security standard using at least part of the transferred security data as input. Preferably, the first security standard corresponds to a 2G standard, basically the GSM standard and the second security standard at least in part corresponds to a 3G standard such as the UMTS standard, and/or the IP Multimedia Sub-system (IMS) standard.

摘要： A method for establishing a security association between a client and a service node for the purpose of pushing information from the service node to the client, where the client and a key server share a base secret. The method comprises sending a request for generation and provision of a service key from the service node to a key server, the request identifying the client and the service node, generating a service key at the key server using the identities of the client and the service node, the base secret, and additional information, and sending the service key to the service node together with said additional information, forwarding said additional information from the service node to the client, and at the client, generating said service key using the received additional information and the base key.

摘要： The present invention relates to establishing security within an ad hoc network. Such ad hoc networks do not have on-line connections to a particular server for getting desired public keys or certificates, thereby requiring them to create trust relations among their respective nodes wherein some of the nodes have a mutual trust relation to each other, thus constituting a trust group. When a particular candidate node desires to join the trust group, an X-node is identified, being a member of a trust group and having a trust relation with the candidate node. The X-node then certifies the candidate node and establishes and distributes trust relations between the members of the trust group and the candidate node.

摘要： A solution making it possible for one telecommunication network operator (10′) to act as intermediate distributor or administrator of a content provider (60) for a multitude of operators (20) is presented. The content provider (60) has a single relation to the central operator (10′), in turn having relations to other operators (20). It is thus possible for the content provider (60) to reach all users (30) of all operators (10′, 20) through a single relation to that operator (10′). The content provider (60) provides service content, e.g. media content. A list of targeted users (30) or subscribers is compiled. The central operator (10′) collects necessary subscriber attributes (80), such as position, device information and access properties, from the other operators (20). The content is modified according to the collected attributes (80), and the content is distributed to the subscribers (30) in the best possible way.

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.
