摘要： A method is proposed for providing a mobile terminal associated with a user with access to a visited Internet Protocol based mobile communication network. The mobile terminal generates a network information element that comprises a home network identifying element that identifies a home network of the user, and a domain name of the visited IP based mobile communication network as a base domain identifier. The mobile terminal then provides this special network information element to the visited IP based mobile communication network, which executes a subscription generating procedure for generating a subscription for the user upon recognizing the special network information element and provides the mobile terminal access based on the generated subscription.

摘要： A method of facilitating access to services of an IP Multimedia Subsystem,by users groups that require alternative handling in relation to the standard handling of IP Multimedia Subsystemusers. Functioning instructions are added to the user group s subscription maintained in the IP Multimedia Subsystem, instructing nodes in the IP Multimedia Subsystemto adapt their standard functioning for this specific group of users. The instructionsin a subscription of a specific user group, providea node of the IP Multimedia Subsystemthat does no longer need to be specific for certain types of users,but has a standard way of operation,that is modified by instructions for dedicated operation for only that specific user group. In further aspect embodiments are disclosed providing improved solutions for known problems of IP Multimedia Subsystems making use of functioning instructions included in the subscription.

摘要： The invention proposes a powerful and inventive combination of stateless and state-full techniques to enable reduced overall key management messages. A set of encryption keys is created based on a stateless subset cover scheme, where each user is associated with a leaf in the subset cover scheme. A basic idea according to the invention is then to establish a state key and a corresponding state representing a subset of users that have the state key and a subset of users that do not have the state key, and determine a subset cover based on information representative of the established state. Finally, a group key management message can be determined at least partly based on the calculated subset cover. The introduced state opens up for efficient subset cover calculation, reducing the size of the key management message.

摘要： The invention generally relates to management of cryptographic key generations in an information environment comprising a key-producing side generating and distributing key information to a key-consuming side. A basic concept of the invention is to define, by means of a predetermined one-way key derivation function, a relationship between generations of keys such that earlier generations of keys efficiently may be derived from later ones but not the other way around. A basic idea according to the invention is therefore to replace, at key update, key information of an older key generation by the key information of the new key generation on the key-consuming side. Whenever necessary, the key-consuming side iteratively applies the predetermined one-way key derivation function to derive key information of at least one older key generation from the key information of the new key generation. In this way, storage requirements on the key-consuming side can be significantly reduced.
摘要翻译：本发明总体上涉及信息环境中的密码密钥世代的管理，该信息环境包括产生密钥信息并将密钥信息分发给密钥消费端的密钥产生端。本发明的基本概念是通过预定的单向密钥导出函数来定义密钥生成之间的关系，以使得可以从较晚的密钥有效地导出较早的密钥世代，而不是以其他方式导出密钥。因此，根据本发明的基本思想是在密钥更新处将旧密钥生成的密钥信息替换为密钥消费侧的新密钥生成的密钥信息。在必要时，密钥消费方迭代地应用预定单向密钥导出函数以从新密钥生成的密钥信息导出至少一个较旧密钥代的密钥信息。通过这种方式，可以显着减少关键消费方的存储需求。

摘要： The invention relates to password-based authentication in group networks. Each device (42) has an authentication token irreversibly based on the password. The authentication involves a first device (42-1) at which the password P is entered and a second device (42-2) towards which the authentication occurs. The first device determines a check token M j for the second based on the password and its own authentication token R I and this check token is sent to the second device, where it is compared with the athentication token of that device. The procedure may include update of a device to exclude a non-trusted device from the group or change the password. Advantageous features are that the information in one device does not allow retrieval of the password and that the password is only exposed at one device, and only temporarily, during the authentication.
摘要翻译：本发明涉及组网中的基于密码的认证。每个设备（42）基于密码不可逆地具有认证令牌。认证涉及输入密码P的第一设备（42-1）和发生认证的第二设备（42-2）。第一设备基于密码和其自己的认证令牌RI来确定第二个检查令牌Mj，并且将该检查令牌发送到第二设备，在该位置与该设备的认证令牌进行比较。该过程可以包括更新设备以从组中排除不可信设备或更改密码。有利的功能是，一个设备中的信息不允许检索密码，并且该密码仅在一个设备上公开，并且仅在临时认证期间暴露。
