摘要： An IMS system includes an IMS initiator user entity. The system includes an IMS responder user entity that is called by the initiator user entity. The system includes a calling side S-CSCF in communication with the caller entity which receives an INVITE having a first protection offer and parameters for key establishment from the caller entity, removes the first protection offer from the INVITE and forwards the INVITE without the first protection offer. The system includes a receiving end S-CSCF in communication with the responder user entity and the calling side S-CSCF which receives the INVITE without the first protection offer and checks that the responder user entity supports the protection, inserts a second protection offer into the INVITE and forwards the INVITE to the responder user entity, wherein the responder user entity accepts the INVITE including the second protection offer and answers with an acknowledgment having a first protection accept. A method for supporting a call by a telecommunications node.

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 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 key. 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 in their respective leg to said intermediary.

摘要： In a radio telecommunication system, the performance of a mobile unit can be significantly improved during a hand-over procedure by reusing existing security associations that correspond to the mobile unit. By reusing existing security associations, a mobile unit can begin secure communications immediately following the hand-over. Otherwise, and in accordance with conventional practice, the mobile unit will have to undertake the time consuming task of renegotiating the required security associations, before it can begin transmitting and receiving secure communications.

摘要： A first data handling node (304) is configured to verify data received in a data distribution network with multiple data handling nodes forming a distribution path of a network topology, by obtaining tag information from a hash server (306). The first data handling node (304) receives data (D3) and a hash tag (H3) from a second data handling node (302). The received data (D3) and hash tag (H3) have been generated by the second node based on a previous hash tag (H1, H2) generated by a preceding third data handling node (300a, 300b). The third node has delivered data (D1, D2) to the second node, and the received data (D3) has been generated by the second node based on the data (D1, D2) delivered by the third data handling node. The first data handling node (304) verifies the received data (D3) based on the tag information from the hash server, which indicates whether the received hash tag (H3) corresponds to a “valid hash tag” (Hx) which is calculated by applying a predefined hash algorithm on the previous hash tag (H1, H2). When the received tag corresponds to the valid tag, the data is verified as trustworthy and not faked or manipulated.

摘要： A method and arrangement in a multimedia gateway connected to a multimedia service network, for providing access to multimedia services for communication devices connected to a private network. In the multimedia gateway, a communication unit receives a request from a device in the private network for a public identity associated with the multimedia gateway. An identity manager then selects and allocates an associated public identity from a pool of public identities associated with the multimedia gateway which have been predefined as valid in the multimedia service network. The communication unit then registers the device by activating the allocated associated public identity in the multimedia service network. Thereby, the multimedia gateway can establish a multimedia session on behalf of the device, using the allocated associated public identity.

摘要： In a mobile, wireless telecommunications network, communications relating to a mobile terminal can be protected during a handover of the mobile terminal from a first access point to a second access point. This may be accomplished by transmitting a security token from the first access point to the mobile terminal, and then from the mobile terminal to the second access point, over the radio interface. Thereafter, the security token is transmitted from the first access point to the second access point through the fixed network to which both the first and the second access points are connected. The communications link between the mobile terminal and the second access point needed to achieve secure handover is then established only if the second access point determines that the security token received from the mobile terminal matches the security token received from the first access point.
