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.

The present invention relates to a method and an operator network node for enabling a user-defined DRM domain of *SIMs hosted by *SIM-enabled devices. The operator network node is connectable to a *SIM based device and to a content provider node, and comprises means for establishing a secure channel between a *SIM-based device and an operator network node, means for creating a DRM domain defined by at least one user of *SIM-based devices, means for receiving at the operator network node a registration request from the *SIM-based device to register the *SIM of the *SIM-based device into the created user-defined DRM domain, means for registering at the operator network node the *SIM of the *SIM-based device into the registered user-defined DRM domain, and means for making the registered information associated with the user-defined DRM domain available to the content provider. The invention also relates to a further method and the content provider comprising means for accessing in the operator network node registered information associated with a registered user-defined DRM domain comprising *SIMs of a user, and means for establishing a content provider defined DRM domain comprising at least one of the *SIMs of the user-defined DRM domain.

A method of authenticating access to a service comprises: a) receiving at a mobile terminal, over a bi-directional near-field communication channel between the mobile terminal and a browser, at least part of the identifier of a service; b) comparing, at the mobile terminal, at least part of the identifier received at the mobile terminal with a set of identifiers stored in the mobile device; and c) authenticating access to the service on the basis of whether at least part of the identifier received at the mobile terminal matches an identifier in the set. The mobile terminal may stored a set of URLs, and may compare a received URL (or part URL) with the set of stored URLs. It may generate an alert to the user if at least part of the URL received at the mobile terminal does not match a stored URL. User names and keys are not required to be stored on the web-browser, so the web-browser does not need to maintain a password database. This improves security, since a password database would be vulnerable to malicious code.

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.
