摘要： A method of delivering an application key or keys to an application server for use in securing data exchanged between the application server and a user equipment, the user equipment accessing a communications network via an access domain. The method comprises running an Authentication and Key Agreement procedure between the user equipment and a home domain in order to make keying material available to the user equipment and to an access enforcement point. At least a part of said keying material is used to secure a communication tunnel between the user equipment and the access enforcement point, and one or more application keys are derived within the home domain using at least part of said keying material. Said application key(s) is(are) provided to said application server, and the same application key(s) derived at the user equipment, wherein said access enforcement point is unable to derive or have access to said application key(s).

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 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。

摘要： In a procedure for delivering streaming media, a Client (1) first requests the media from an Order Server (3). The Order Server authenticates the Client and sends a ticket to the Client. Then, the Client sends the ticket to a Streaming Server (5). The Streaming Server checks theticket for validity and if found valid encrypts the streaming data using a standardized real-time protocol such as the SRTP and transmits the encrypted data to the Client. The Client receivesthe data and decrypts them. Copyrighted material adapted to streaming can be securely delivered to the Client. The robust protocol used is very well suited for in particular wireless clients and similar devices having a low capacity such as cellular telephones and PDAs.
摘要翻译：在递送流媒体的过程中，客户端（1）首先从订单服务器（3）请求媒体。订单服务器对客户端进行身份验证，并向客户端发送故障单。然后，客户端将该票发送到流服务器（5）。流媒体服务器检查电子邮件的有效性，如果发现有效使用标准化的实时协议（如SRTP）对流数据进行加密，并将加密的数据发送给客户端。客户接收数据并对其进行解密。适用于流媒体的版权材料可以安全地传递给客户端。所使用的鲁棒协议非常适合于特定的无线客户端和具有低容量的类似设备，例如蜂窝电话和PDA。

摘要： A technique for handling an access from a user equipment (110) accessing an application function (150) is provided. As to a method aspect of the technique, the access is received via a packet core network (140) of a mobile telecommunications network (100).The application function (150) determines that the access from the user equipment (110) fulfills a predefined access pattern. The application function (150) triggers sending of a control message to the packet core network (140) in response to the determination. The control message controls the packet core network (140) to terminate a session with the user equipment (110).

摘要： A method in an IP multimedia subsystem, IMS, of a telecommunications network. The loss of a secure association between a P-CSCF of the IMS and a user equipment, UE, served by the P-CSCF is detected, or a UE is relocated from a further P-CSCF to the first mentioned P-CSCF. The first mentioned P-CSCF sends a reregistration request to the UE; receives a SIP REGISTER message from the UE; and performs P-CSCF registration with the UE including establishing a new secure association with the UE.

摘要： A method in a proxy call session control function, P-CSCF, of handling an unauthenticated emergency call originating from a roaming user equipment, UE, which is not attached to the P-CSCF. The P-CSCF receives a SIP INVITE request from the UE, the INVITE request relating to the unauthenticated emergency call, and determines an IP address of the UE. The P-CSCF sends an identity query to a policy and charging rules function, PCRF, indicating the IP address of the UE and requesting other identifiers of the UE;, and receives one or more other identifiers of the UE from the PCRF. The P-CSCF constructs a TEL and/or SIP uniform resource identifier, URI, for the UE on the basis of at least one of said other identifiers, inserts the URI into the SIP INVITE request, and sends the SIP INVITE request to a public safety answering point, PSAP. Also provided are corresponding methods in other nodes and for authenticated emergency calls, and apparatus for implementing the methods.
